Conservation of Maps in the digitisation project: Qatar Foundation Partnership – Part 1

The British Library Qatar Foundation Partnership (BLQFP) is a digitisation project that began in 2012 to create the Qatar Digital Library (QDL). For over ten years this free bilingual online portal has been fed from the British Library´s collections related to the history of the Persia Gulf and scientific manuscripts of the Arabic-speaking world. The items that are selected and digitised include India Office Records, maps, personal papers, catalogued and uncatalogued Arabic manuscripts, sound and video recordings, photographs and much more.

At the beginning of 2022, in the last part of Phase 3, 120 maps entered the digitisation workflow. One of the first stages of the workflow is conservation assessment, where items are assessed and stabilised for safe digitisation and handling. The majority of the maps needed minimal intervention, with only 5 needing a more interventive conservation approach. This blog will focus on the treatment of the following maps: IOR/X/3174, IOR/X/3150/2, IOR/X/9921, IOR/X/10065 and IOR/X/10066.

In order to organise our treatments, we divided the maps into 2 groups according to their similarity in manufacture, their condition and treatment strategy. The first group, which is the focus of the first part of this blog, included IOR/X/3174, IOR/X/3150/2, IOR/X/9921, and had a silk ribbon sewn on the edges of each map. The silk ribbon was placed to protect and give a nice finish to the edge of the maps, since all 3 have cloth as a backing support. We think this was placed because either the paper is too big, or small pieces of paper have been attached together, so the secondary support would give the primary paper support extra protection and ease handling. The silk ribbon protects the edge of the maps and helps to stop the fraying of the textile. We talked to the map’s curator from the Qatar team, Nick Krebs, and he mentioned the possibility that these ribbons were placed when the maps were at the India Office Records.

On these 3 maps the silk ribbon was detached from the edges in some places, due to a broken thread that used to attach the ribbon to the map. Also, the ribbon was very thin and fraying, causing further losses. Apart from this, the general condition of the maps was good.

As paper and book conservators unfamiliar with the treatment of textiles, we took this opportunity to seek advice from the appointed textile conservator at the British Library, Liz Rose. This had the advantage of providing a moisture and solvent free application technique to the damaged silk ribbon, which can be easily damaged by the introduction of moisture. Liz Rose showed us how to prepare the adhesive on crepeline silk and nylon net in the following way:

The adhesive used was a mix 1:1 of two different Lascauxs: 408 HV and 303 HV. The first one dries hard, while the second is extremely elastic and dries tacky. Both are thermoplastic acrylics (AIC - Adhesives & Tapes, 2022), therefore a combination of these two is ideal for reactivating the adhesive with a hot spatula or with solvent (like acetone) to consolidate fragile textiles, depending on the condition of the item.

We prepared two different percentages of the 1:1 adhesive mix, 15% and 25%, to test which of the two had better results on a new silk ribbon. When we had the adhesive ready, this was applied with a brush to a crepeline silk and nylon net, provided by Liz Rose. Fortunately, the crepeline silk and nylon net were already dyed in different tones of green and we only needed to choose the best tone to suit the different ribbons.

Five pieces of crepeline rest on a map, toned in varying shades of blues, greens and browns.

Once the adhesive applied to the crepeline silk and nylon net had dried, it was cut to the desired size and heated with a hot spatula to mend the damaged parts of the silk ribbon. As mentioned before, we first tested it on a new ribbon and over cotton textile. From these tests, we determined the best percentage of adhesive to use was 15%, and the appropriate length of time to reactivate the adhesive was 1 minute. We observed in this test that the nylon net melted with both the new ribbon and cotton fabric if heated for too long and if the spatula was too hot. Also, we realized that the nylon net consolidation did not have good results when the consolidation needed to be folded back, due to the fact that some of these maps are oversized and folded multiple times. This was not the case with the silk crepeline, therefore we decided to use this, because we had better results with it being a more sympathetic material with the silk ribbon, and giving us the most satisfying visual result.

Rows of the crepeline have been applied to a white cotton and the new silk ribbon. These test pieces have been arranged in three columns, with writing indicating the percentage of 15, a temperature of 4 degrees, and reactivation times of 1 minute, 30 seconds, and 1 minute 30 seconds.

Treatment on the maps: IOR/X/3174, IOR/X/3150/2, IOR/X/9921

After completing tests on the silk samples, we dry cleaned the recto and verso of the maps and then the most damaged sections of silk ribbons were delicately removed from the maps by cutting the sewing stitches. Next, we consolidated the bond between the paper and the lining cloth using Japanese tissue and wheat starch paste.

We then applied the pre-coated crepeline silk to the inside of the ribbon using a hot spatula to consolidate the fragile segments. The width of the crepeline consolidation was cut to fit in between the edges of the ribbon and its length was cut into small sections (no longer than 7 cm). We noticed that longer repair creates distortion. The crepeline segments were overlapped by 1 mm when it was necessary to cover a longer part.

In some cases, where the ribbon was particularly damaged, we also needed to consolidate the outside of the ribbon. This helped to further reinforce the zones where the ribbon was completely broken and the zones where the ribbon was folded as the map had been stored in this way.

As the ribbon was attached to the map folded, we applied the crepeline on the outer part on a folded ribbon. The pre-coated crepeline was folded and fitted over the original folded ribbon and then applied with the hot spatula one side at a time.

The edge of a map is shown with the ribbon beneath and the crepeline on top of the ribbon.

After consolidating the damaged ribbon, we then re-attached the consolidated ribbons onto the maps by sewing them back in place using a green silk thread, similar to the original.

Finally, after documenting the treatment, the smaller maps (that fit flat in the storage drawer) were placed in a Melinex sleeve to protect them from frictions and limit direct handling. The oversized maps were placed in a blue folder to protect them from friction in the storage.

Conservation of the Granville Archive papers

Veronica Zoppi, Conservator

General description:

The Granville Archive, recently acquired by the British Library, includes a vast collection of letters and papers relating to British national life in the 18th and 19th centuries. These papers had been unknown to researchers until their acquisition and shed particular light on the personal and political lives of aristocratic women of the period.

Two caches of these letters recently arrived in my care in the conservation studio, Add Ms 89382/3/1 and Add MS 89382/3/4. Add Ms 89382/3/1 contains Georgiana Duchess of Devonshire own private correspondence with her husband and discussion of the latest books and politics, perennial concerns about reputation, scandal and money. Add MS 89382/3/4 consists of the original letters of the Duchess to her daughter Harriet including the ‘Blood letter’, written with the duchess’ blood.

Assessment of characteristics, condition and risks during use:

When brought for conservation, the letters (written with iron gall inks), were housed unbound within two folders. Nevertheless, some letters retained evidence of past interventions. These include a sewing along the left edge or along the centre-folds, and gilded edges which suggests that they had been previously bound. Enclosed between the letters were three paper wrappers. Each contained a hair lock belonging to one of the Duchess’ children and to her sister.

The letters exhibited surface and ingrained dirt - especially along the edges -, discolouration, edge tears, and losses. Some of the seals used to close the letters had cracks. The hair locks, loose in their paper wrappers, were brittle. In their present state both the letters and the hair locks were not fit for use as they were at risk of further damage, loss, and theft.

Aim of the conservation treatment and Planning and decision-making process:

The aim of the conservation treatment, as discussed with the curators, was to make these collection items available to researchers for consultation and possibly for display in an exhibition.

The conservation challenge posed consisted of balancing the preservation of the integrity of these vulnerable items - including their material and non-material aspects and values - with their use.

The decision-making process took into account many aspects discussed and agreed with the curators and the cataloguer. Planning of the work involved a vast range of considerations including the condition of the items, their access requirements and frequency, intended uses after treatment, storage, available time for treatment and resources. Other considerations regarded the conservation needs of the items, the goal of the treatment and practical techniques for housing and mounting for the letters and the hair locks with their wrappers respectively. Expectations about the functionality and appearance of the items after treatment were also discussed.

Documentation and practical treatment:

The photographic and written documentation about the items’ materiality and condition recorded how the items were before treatment and will be used in the future, should these items will undergo further conservation treatment.

The practical conservation treatment was carried out using archival quality, durable and reversible materials which have been long used in conservation, such as for instance mounting boards and end-leaf paper.

The hair locks and paper wrappers:

For the hair locks a stabilisation technique was borrowed from the conservation of textiles and historic wigs, as it was considered the most unobtrusive and safest way to preserve these delicate items. A mock-up was prepared to test the stabilisation and mounting technique of hair before applying it to the collection items.

This technique consisted in arranging the hair locks on a polyester conservation net and stabilising them by weaving a polyester thread through several layers of hair at various depths. Once the sewing was complete, the net of each hair lock was then mounted by means of Japanese paper strips, between mounting boards, together with its paper wrapper.

Polyester windows on both sides were used for the paper wrappers as they retained evidence on both recto and verso, for instance the creases of their original folds, or handwritten notes. Because of their weight, each mounting board solution included two guards made of Japanese paper reinforced with linen on the left edge to be joined to the new binding through holes. The mounting boards were used because they offered rigidity during handling by researchers, thus avoiding damage to the brittle historical hair. The polyester windows enabled both hair and wrappers to be safely looked at without being touched.

The letters:

The surface cleaning of the non-written edges of the letters was carried out with a vulcanised smoke sponge and a soft brush to allow for a gentle cleaning of the paper supports. The smoke sponge has the additional advantage of trapping the dirt within its structure, without leaving residues in the paper support. For the tears repairs, re-moistenable tissue prepared with Japanese paper and wheat starch paste and methylcellulose as adhesives was chosen because it has the benefit of releasing a slow and controlled amount of moisture in the paper supports. This is especially useful in the presence of iron gall inks whose degradation speeds up with humidity. Japanese Kozo paper has long fibres, thus offered a strong bond with the paper support of the letters, has neutral pH and is stable over time. Losses that could cause further damage during handling were infilled with Kozo Japanese paper.

The cracks of the seals were assessed as being stable, that is, at low risk of further damage when handled carefully. For this reason, no treatment was considered appropriate.

Next, the letters were attached - staggered, with wheat starch paste - along their left edge to archival paper end-leaf guards. A pamphlet was sewn through the centre-folds with linen thread. The sewing thread used to keep some loose letters together, was cut as it was causing damage to their paper supports during handling, but was kept in place.

The Blood letter was given additional protection in a polyester pocket, because of its historical value and potential risk of damage during handling.

Where the text of some letters ran up to the central folds on both recto and verso, the end-leaf paper guards attached to the letters, were shaped to avoid concealing the text.

The binding:

When dry, the guarded letters and the mounted hair locks and wrappers, were bound in two post-binders. This type of binding was chosen over others, because of its versatility. It allows for housing a

variety of letters and if necessary, for the easy temporary removal of the required letters or mounting boards should they be accessed separately - for instance for an exhibition.

Conservation of Thurloe’s State Papers

You may have seen a recent conversation sparked by one of our ‘Before and After’ conservation posts on the Library’s main social media channels. This may have got you wondering how conservators decide on the best treatment methods for collection items. In this blog we are going to dive deeper into the treatment of the volumes pictured in the Before and After images, giving further insight into the many considerations a conservator makes when treating an item.

Conservators at the British Library have to balance the future use of the book with the preservation of historic evidence. In a working library like ours, books are used by readers and our treatments must take this into account. The set of manuscript volumes pictured in the recent social media post are an example of this decision-making process and posed an interesting yet familiar conservation challenge.

The Thurloe State Papers volumes I-VII date back to 1742 and arrived in our conservation studio in poor condition. Each book exhibited similar degrees of damage and deterioration including detached boards, loss of endbands, severely degraded leather on the spines, splits in the textblock with damage to the sewing structure, and very worn and abraded boards.

These are highly requested collection items, and without thorough treatment would no longer be available for reference. Enabling access to readers is one of the BL’s core purposes and our Conservation department works hard to facilitate public access to our national heritage by ensuring that our books are in good condition in order to be handled and read without risk of further damage to the bindings. 

 

The seven volumes photographed with their textblocks (rather than spines) facing us. The pages have a marbled appearance and six of the seven books have cotton string holding the books together.

A birds eye view of the top of the books' textblocks.
The top of the volumes showing ingrained dirt on the textblock and the loss of all the leather headcaps and silk endbands apart from a few remaining fragments.

 

Planning a conservation treatment involves a complex range of considerations from different fields including material and chemical science, preservation, historical context, value, ethics as well as the suitability of practical techniques and available time and resources. 

We follow a Code of Ethics which helps inform the process and to ensure that we are asking the right questions. Conservators use their professional judgement in combination with discussions with curators about the context of the items within the Library's historic collections and so it is a collaborative approach.

The most common form of damage that we find in Library collections is board detachment. This prevents books from being issued to readers due to the risk of damage to the textblock or loss of material.  There are a variety of causes of detached boards, including ageing of materials and general wear and tear from use.

Because a book is a physical object with moving parts, the action of opening and closing the boards can put a strain along the joint area, which can cause the covering material and sewing supports to break - resulting in detachment of the boards. 

There are various techniques used to reattach book boards.  Often, a volume needs to be 'rebacked' as part of the process of reattaching the boards; repairs are made to the textblock, sewing structure and endpapers and then new spine coverings are applied and carefully inserted under the existing leather on the boards. This process necessitates the removal of the existing spine coverings as it is often the case that strong and durable repairs cannot be undertaken without access to the spine of the volume.

An ideal conservation treatment would involve the re-use of original material wherever possible in order to minimise any aesthetic change to the item. When rebacking volumes it is our practice to, where appropriate, reattach the original spine pieces back onto the new spine. This retains the visual appearance of the book whilst providing a strong and durable repair. However, if the original material is too degraded to be reattached to the book - as in the case of the Thurloe State Papers - we need to consider other options.

The original spine leather was degraded and worn away with splits and cracks around the raised sewing supports as well as up and down the spine.
A close-up of the bottom of a spine of one of the volumes showing wear and tear.
Many of the endbands and headcaps were missing on all seven volumes. 

 

As you can see from the close-up photograph, the original spine leather was very thin, degraded and fragmented. It was also adhered directly onto the spinefolds of the textblock paper as part of the 'tightback' binding structure making them very difficult to remove intact due to their fragility.

If we did reattach these spine panel fragments they would, in a very short time, wear away through use and be completely lost to researchers now and in the future.  So whilst we couldn’t reuse the spine panels, we did carefully remove and store them with the collection item. This way, they are preserved along with the bindings for future reference.

 

The spine fragments have been placed on a piece of card and sealed in a polyester sleeve for protection.
The remaining spine fragments were too fragile to be reattached and have been stored with each volume in its protective box.

 

Sometimes ‘Before and After’ photographs can look like quite a dramatic change to the object, but in this case only the spines of these volumes required replacement. The original boards were reused even though they were severely damaged.  The worn-down board corners were rebuilt and re-covered in new leather. Along the exposed and abraded board edges, the original leather was carefully lifted and new leather inserted underneath in order to preserve as much of the gold tooled edge decoration as possible.

Where the board edges were exposed, new leather was carefully inserted underneath the existing leather whilst retaining the gold tooled edge decoration.

 

The materials used in our conservation treatments are selected for their proven archival qualities, strength and durability.  Materials such as linen fabric and threads, handmade paper and wheat starch paste have been long used in traditional bookbinding, as is the ‘rebacking’ process of covering spines with new leather or cloth and decorating with gold leaf.

Whilst considering how to carry out the finishing on the Thurloe State Papers, it was decided to use a simplified version of the gold leaf lettering and decoration. This was partly because we do not have the historic finishing tools used by the original binder to be able to replicate the decoration exactly.  Secondly, this hand craft is highly skilled and very time-consuming - and we have to justify the amount of time spent on decorating individual volumes when there are so many other books needing conservation in the Library.

Conservators take great care to match the colours of new materials added so that they appear sympathetic to the existing material. In this case, the new spine labels were made of red leather and even the endband threads dyed to match the originals.

 

Endband sewing is in progress here, with a needle and orange thread being pushed through in a green, orange, green, orange thread pattern.
Primary endbands were sewn in plain linen thread followed by secondary endbands in silk, dyed pink and green to match the original thread found in the volumes.
The orange and green endband is complete.

We enjoyed reading the range of comments these Before and After photos inspired. It’s great to see that so many people care about the preservation of historical books - and the range of comments show that not only that there are a huge number of factors to weigh up in making treatment decisions, but also that several different approaches could be used to achieve a similar outcome.

Conservators have to consider that books are mechanical objects, not just historic artefacts, and have moving parts that need to function in conjunction with each other in order for the book to be used. This is often dependent on the construction materials and methods used and is one of many other factors, such as historical context and the status of the object, which are taken into consideration when planning conservation treatments at the British Library.

If readers are interested in learning more about books as 'dynamic objects', there was a recent Institute of Conservation talk about this very subject, which you can watch on the Icon YouTube channel.

Keep an eye out for an upcoming blog post which will discuss more broadly the varying approaches to conservation decision-making in the Library’s Conservation department.

Iron gall ink on paper: Saving the words that eat themselves

Paul Garside & Zoë Miller

Iron gall ink (IGI) will be familiar to most of us as the characteristic brown ink that we associate with the authenticity and softly aged aesthetic of historic documents.  It is the most important writing and drawing ink in Western culture, initially emerging in the first centuries AD and continuing in widespread use until the 20th century.  Many thousands of examples of its use on both parchment and paper can be found in the British Library’s historic collections, ranging from Treasures and other important items, such as the Codex Sinaiticus, the Lindisfarne Gospels, Magna Carta, manuscripts penned by Henry VIII and the works of famous diarists such as John Evelyn, to more commonplace letters, notes, musical scores and records. And IGI documents will form a vital part of our forthcoming exhibition Elizabeth and Mary: Royal Cousins, Rival Queens .

Figure 1: Three sheets of paper with dark brown iron gall ink.  The ink on the opposite sides of the papers is starting to show through.

[Figure 1] An example of IGI on paper (Walpole Papers 73898).

However, IGI may damage the surface on which it is written, and paper is at particular risk, leading to characteristic haloing, fragility, fracturing and areas of loss. It has been estimated that up to 80% of European archives contain items at significant risk of this problem. The potential to cause damage has been known for a long time: in 1765 the English chemist William Lewis published a treatise on the stability of IGI, and over one hundred years ago the Vatican Library warned about the impending destruction of many precious manuscripts from the effect.  However, the ink remained popular, not least for its durability and permanence (it adheres firmly to the substrate, and resists rubbing and washing, unlike carbon inks), but also because it was easy and cheap to make, using a wide variety of historic recipes.  Most recipes are based around four principal components: gallic acid, derived from oak galls; iron(II) sulphate (often referred to as green vitriol); water or an aqueous medium; and a binding agent, such as gum Arabic.  When these ingredients are mixed, the acid and the iron sulphate react together then oxidise to form iron(III) gallate, which is strongly coloured; the ink is typically a dark slate grey when first formed, turning brown or orange as it ages.

Figure 2: A magnified image of iron gall ink on paper, lit from the back, showing dark haloing around the text and areas of loss from regions of heavy ink.

[Figure 2] The effects of IGI corrosion.

Why does this ink cause damage? There are two main, interlinked processes. Sulphuric acid is a by-product of the reaction which creates the ink, and this can lead to hydrolysis of the cellulose that forms the building blocks of paper. Excess iron(II) ions, from the initial ingredients, can also speed up the oxidative degradation of cellulose. In conjunction, these two effects are often referred to as IGI corrosion, and in extreme cases inked lines can actually crack and drop out of the paper surface. We have found that imbalanced recipes and impure ingredients can complicate the aging process and damaging properties of these inks, resulting in wide visual differences. The Instituut Collectie Nederland (ICN) has developed a four level system to categorise the damage caused by IGI , from 1 to 4 ('good' to 'very poor' condition), as shown in these examples from the BL's collection:

Figure 3: The four ICN condition levels, illustrated with examples from the British Library’s collection.

[Figure 3] The condition of IGI on paper: 1 (good condition - no/light discoluration and stable to handle); 2 (fair condition - dark discolouration around ink, with no immediate mechanical damage, but this could result from handling); 3 (poor condition - some mechanical damage around ink, and handling is likely to cause more damage); 4 (very poor condition - serious loss of substance, which will be exacerbated by handling).

Historically, treatments for paper documents suffering from IGI corrosion were much more invasive than would now be considered acceptable, including processes such as lamination, simmering or aggressive de-acidification.  Greater understanding of the material and developments in conservation science have allowed a more tailored, less invasive range of options. For some documents, aqueous treatments will be the most appropriate choice: the items are immersed in a calcium phytate solution, to bind and isolate damaging iron(II) ions, accompanied by gentle de-acidification, to remove existing acids and provide an alkaline reserve.  For other documents, low moisture repairs (using gelatine adhesive, which resists IGI attack as well as providing mechanical stabilisation) or the more conventional support of physical damage will be better choices.  The following chart gives an overview of our thought-processes when considering the best approach; we developed it to help visualise the process and explain our decision-making to colleagues.  As can be seen, we would consider a wide range of factors, including:

  • The state of the IGI and the damage it has caused, assessed using the ICN categorisation.
  • The overall condition of the item, taking into account any signs of damage to its composition or structure, the presence of vulnerable components such as water-sensitive materials, and its general stability and ease of handling.
  • Our 'risk appetite' for the item.  This represents our willingness to accept risks when treating the object, and is related to factors such as cultural value, historic significance and rarity. This would obviously be very low for Treasures items, but even with objects assigned a higher risk appetite, we would not act recklessly or without planning – we may, however, be willing to consider more interventive or extensive treatments to enable the item to be more widely accessed.

[Figure 4] Decision-making for the treatment of IGI on paper.

This scheme is not prescriptive, however, and each object would be assessed and treated on its own merits. Furthermore, sometimes the best conservation decision is to carry out no treatment at all, and in all cases our work is underpinned by good preventive conservation, in the form of appropriate storage, suitable environmental conditions and sympathetic handling.

Conservation for Digitisation: A collaboration with the Palestinian Museum

Amy Baldwin, Book Conservator & Jessica Pollard, Digitisation Conservator

In April and May 2019 we had the pleasure of welcoming two members of staff from the Palestinian Museum, Baha Jubeh, Conservation Manager and Bara Bawatneh, Conservator, to the British Library as part of a collaborative Conservation for Digitisation project funded by the Cultural Protection Fund administered by the British Council. Over a six week period we carried out training in conservation methods specifically for digitisation to assist in the successful completion of the project, the aims of which were:

  1. To establish the first paper-based conservation studio in the West Bank
  2. Training and capacity building for staff from the Palestinian Museum
  3. Conservation and Preservation of 3000 paper-based endangered collection items
  4. Education and advocacy activities

The relatively short time period but large amount of information to cover meant an intensive and busy six weeks were spent in the conservation studios. Our priority was to equip them with the necessary skills to complete the project while keeping intervention to a minimum, and although we had to be realistic with the timescale we also needed to be flexible to adapt to their specific needs. The training schedule included, but was not limited to, an introduction to paper conservation; the practicalities of setting up a conservation studio; mould identification and remediation; and developing an understanding of the end-to-end digitisation process.  Time spent with colleagues from imaging and curatorial departments, as well as trips to Windsor Castle and The National Archives conservation studios, complemented this practical training and gave further insight into the complexities of digitisation projects.

We made a return visit to the Palestinian Museum in Birzeit, Ramallah in June 2019. The Museum is housed in a stunning award-winning building surrounded by gardens which illustrate the history of agriculture and plants in Palestine, and the paper conservation studio is the first of its kind on the West Bank. At the time of our visit the conservation focus was on the Museum’s Digital Archive project, which digitised thousands of paper items from endangered collections belonging to small institutions and private individuals. These items were loaned to the Museum for the duration of the digitisation process. Many had been kept in private homes for many years, and the condition varied from a light layer of surface dirt to large tears and water damage.

Three volunteers had been recruited to assist with the project, and we were able to collaborate with the Museum’s conservator in providing training for them. We only had four days together, so we had to ensure that the volunteers’ skills were utilised effectively, and we knew that the time available for them to practice their new skills before starting work on loan items would be very short. With this in mind, the volunteers’ training focused on surface cleaning, flattening and simpler paper repairs. This left the Museum’s conservator to concentrate on items with more complex damage, including photographs, which require different treatment to other paper-based items.

The final phase of the project took place in late 2020. Its focus was on those items that were classified as badly damaged and had so far been left untreated, the majority of which were bound manuscripts. Further training was required to assist in completing the treatment of these item, however the global pandemic put a stop to any hope of providing UK based in-person training so we turned our attention to what could reasonably and safely be taught virtually. The original training sessions, largely focusing on wet treatments and simple book repair methods, had to be adapted with a new emphasis on handling and imaging fragile manuscripts safely with limited conservation intervention. Using a mixture of online presentations, pre-recorded demonstration videos and digital handouts we provided training in the following: handling fragile items for digitisation; consolidation and repair of mould-damaged paper; health and safety for conservation; an introduction to book structures; separating pages adhered together; and mould remediation. With no previous experience of carrying out virtual training it was a steep learning curve, especially filming and editing our own videos, and although we had to adapt our initial training proposal and scale-down our expectations, we were incredibly pleased to be able provide training during a difficult period and assist in the completion of a complicated project, which was only made possible due to the enthusiasm, skill and determination of those at the Palestinian Museum.

Lotus Sutra Project: Storage Solutions

Paulina Kralka and Marya Muzart

The Lotus Sutra Manuscripts Digitisation Project at The British Library, is a multi-year project aiming to conserve and digitise almost 800 copies of the Lotus Sutra scrolls in Chinese, with a view to make images and information freely accessible on the International Dunhuang Project (IDP) website. These manuscripts come from a small cave in a Buddhist Cave complex near Dunhuang, in Northwest China, where tens of thousands of documents, paintings and artefacts dating from the late 4th to the beginning of the 11th centuries were discovered in 1900. Out of the 800 manuscripts included in this project, a large portion of them need conservation work.

Depending on the scrolls’ condition, treatment can range from surface cleaning and minor repairs, to lengthy mould remediation and intricate infills to ensure that they are safe for digitisation. With manuscripts in varying states of preservation and size, ranging from 10 centimetres to almost 14 meters in length, they have very different housing needs. Addressing these various housing requirements is part of our conservation work. We take into account our existing storage facilities, and come up with solutions that are best suited for long-term preservation of the collection but are also feasible within the time and budget of a digitisation project. This poses an interesting challenge to us as conservators.

The storage facility for scrolls at the British Library consists of white open shelving or glass enclosed wooden cabinets holding individually boxed scrolls.

Picture 1: Our storage.

Here a conservator is placing a scroll into a pigeon hole. Some of the cabinets have individual pigeon holes for each scroll with the shelfmark noted.

Picture 2: Close-up of the pigeon holes where the scrolls are stored.

The majority of scrolls that arrive in our conservation studio have never been treated before. They are usually tightly rolled on their own or around a thin wooden roller attached to the last panel. This causes tensions and leaves the scroll unsupported where it then becomes prone to distortions, creasing and further mechanical damage when handled. Research and practice show that the larger the rolling diameter, the less likely the scroll is to develop creases and cracks. In order to address this, we always place the scrolls on increased diameter cores after treatment has been completed. These cores are made from acid free cardboard tubes with a 5.5cm diameter, that we cover with a layer of xuan paper 宣纸 using wheat starch paste as an adhesive. The cores help reduce the tensions caused by a scroll being rolled too tightly and also provide it with proper support during handling and storage, minimising the risk of further damage. In addition, each scroll is wrapped in a protective layer of xuan paper, which prevents dust accumulation and surface abrasion.

Here a conservator is unravelling a scroll on a red desk with the aid of a scroll core.

Picture 3: A scroll being handled with the help of a core.

When rolled onto the 5.5cm cores, some of the longer scrolls in the project (typically those over 10 metres long) no longer fit into the pigeon holes of our existing storage. In order to enable the scrolls to still be stored in the existing storage facilities on an increased diameter core, whilst having enough space for safe handling, we have successfully developed a technique of hand-making cores with a smaller diameter of 3.5cm, composed of archival grade kraft paper and wheat starch paste.

A comparison of two scroll cores: the core on the left is wider at 5.5cm while the core on the right is 3.5cm.

Picture 4: Left, the 5.5cm core and right, the 3.5cm core which we hand-make for very long scrolls.

And what about the shortest surviving fragments? They are usually severely damaged. To prevent possible dissociation and further weakening of the paper, we encapsulate them in Melinex pockets. Melinex is an archival grade, glass-clear, thin polyester sheet, which not only helps us protect such delicate fragments but also allows them to be stored flat within custom made folders. Scroll fragments in Melinex are safe and easy to handle as both sides can be easily accessed, whether by our imaging staff during digitisation, or researchers wishing to examine the manuscripts in the reading rooms.

A conservator is encapsulating a scroll fragment between two Melinex sleeves so the scroll lays flat.

Picture 5:  Encapsulation of a scroll fragment in Melinex.

We are lucky that a large number of scrolls in our collection survive with their original wooden rollers still in place. In order to house the rod safely, whilst simultaneously providing appropriate support for the scroll, we have modified our standard core to create a custom-made clamp which fits the original roller inside and increases the rolling diameter. The cardboard core is cut in half; an intricate system of Japanese paper tabs is then pasted down to allow it to open and close smoothly; and, finally, a small groove is cut out to facilitate accommodating the scroll and rolling it onto the core. This clasp core design is adapted from the traditional Japanese wooden roller clamp, known as futomaki 太巻 or futomaki jiku 太卷轴, used for hanging scrolls, but is much more lightweight and economical!

In some instances, the original wooden rod is detached from the scroll, which creates another storage challenge. To avoid any dissociation, we always aim to store the rod together with the scroll. In order to achieve this, we have created small foam inserts that fit the roller in them and placed them inside standard cores. We found that polyethylene pipe insulation tubes are well-fitted for the purpose! Thanks to the Oddy tests carried by our conservation scientist Paul Garside, we know they can be safely used with our collection. The tube is cut in half and hinged on one side with Filmoplast SH cotton tape to allow for smooth opening and closing. The rod, wrapped in a protective layer of xuan paper, is placed inside and secured in place with pieces of cotton tying tape, threaded through small slits cut in the tube. The insert fits inside the core quite snugly, so we place a small tab on the bottom of the tube to facilitate access.

These storage solutions show how our work doesn’t end in the conservation studio. To ensure that the collection is well-preserved for future generations, we have to think beyond just the treatment of the object. This project has enabled us to challenge ourselves in thinking outside the box and approach the various storage issues with innovative solutions.

Lotus Sutra Project: Scroll with Blue Cover

Marya Muzart, Digitisation Conservator, International Dunhuang Project

Digitised scroll after treatment showing a blue cover on the scroll.

Picture 1: Close up of digitised scroll after treatment.

The Lotus Sutra Manuscripts Digitisation Project at The British Library, is a multi-year project aiming to conserve and digitise almost 800 copies of the Lotus Sutra scrolls in Chinese, with a view to make images and information freely accessible on the International Dunhuang Project (IDP) website. These manuscripts come from a small cave in a Buddhist Cave complex near Dunhuang, in Northwest China, where tens of thousands of documents, paintings and artefacts dating from the late 4th to the beginning of the 11th centuries were discovered in 1900. Out of the 800 manuscripts included in this project, a large portion of them need conservation work. This blog post covers the treatment of Or.8210/S.3796 which measures over 10 metres long.  

What is particularly striking about this item is the blue cover or protective flap at the beginning. Whilst it bears a few stains from water damage, the colour is incredibly vivid considering the age of the item. It is unusual in this project to see scrolls which are 100% complete, from the front cover to the very last panel, so having the front cover present, in addition to its striking colour, makes this item quite special. In addition, part of the thin wooden stave on the cover is still present, a silk tie would once have been attached to this, however it is now gone. 

The use of blue paper (typically dyed using indigo) for sutras grew in popularity in China from the Tang dynasty (618–907 CE) onwards, it flourished in Korea and Japan around the same time and can also be found in other cultural traditions beyond East Asia. By the end of the Dunhuang period, and in later Chinese tradition it became common to use silver or gold ink on dark blue paper for the finest manuscripts [1]. See this fragment of scroll Or.8210/S.5720, which is part of our wider collection, as an example. 

Re-use and recycling of paper was a common practice carried out by the monks in Dunhuang [2]. It is possible that the cover of Or.8210/S.3796 was sourced from some left-over paper which had previously been used for one of the finer sutras written on blue paper.

Picture 3: Verso Before Treatment.

The losses which you can see in the before images were a result of historical rodent damage, when the scroll was examined closely small teeth marks could be seen. As the damage occurred when the scroll was rolled, there is a repetitive nature to the losses which get smaller as we move away from the beginning of the scroll. Due to the presence of these numerous large losses conservation treatment had to be carried out in order to stabilise the scroll for digitisation.  

The first step to treatment was creating a blue repair paper to match the cover. At the IDP conservation studio our usual repair papers are hand dyed in relatively large batches using fabric dye, this is so that we always have lots of different tones and colours at hand. However as blue isn’t a typical colour we come across in this project, some experimentation had to be carried out in order to get the correct blue shade for the repair paper.  Dyeing was tried at first using the usual fabric dye, however the right blue hue still wasn’t accomplished after a few attempts, so I decided to tone the paper using a diluted acrylic paint instead, which was more successful and efficient. 

Some repair samples from experimentation laid out on a table.

Picture 4: Some repair paper samples from experimentation.

Finding the correct colour when custom toning repair paper is typically a matter of trial and error. Once I had found the correct combination of colours, I used a Japanese paper which had previously been dyed a yellow tone and this created the perfect base for applying the diluted blue acrylic wash. As the verso of the cover is lighter, once dry, the blue repair paper was then lined onto a lighter, yellow toned paper using diluted wheat starch paste. My custom toned repair paper was then used to infill the losses present on the cover of the scroll. For the remaining losses throughout the scroll, a yellow toned paper was used, this was a much easier source out of our existing repair paper collection!  

As you can see from the after images, the scroll can now safely be handled and digitised by trained internal staff. It is a unique item in the project, which was a pleasure to work on. All in all, a successful treatment! 

The digitised scroll is available to be viewed via this link thanks to Jon Nicholls.

On light: conserving material for our exhibition Unfinished Business: The Fight for Women’s Rights

Alexa McNaught-Reynolds, Conservation Exhibition and Loan Manager

Two of the items selected for display in our exhibition: Unfinished Business: The Fight for Women’s Rights appear to be in good condition but have vulnerabilities that may not be immediately obvious. In Conservation we strive to understand every component of an object in order to recommend the best course of action for their long-term care.

Item 1. NEWS.REG170: Daily Mirror front cover: Tuesday 28th March 2017

Vulnerability: newspaper is not made to last

This is an important item in the exhibition, highlighting how strong working women are still sometimes represented in the media today. Newspapers are produced from poor quality wood pulp that is inherently unstable due to something called lignin, and they are not made to last. Lignin makes the paper acidic and when placed in direct sunlight, as many of you will have seen, newspapers turn yellow and become brittle very quickly.

We strive to protect our newspaper collection by storing them in alkaline buffered material, in a stable environment free from exposure to light sources. These actions significantly slow the degradation process.

But what about when one is requested for exhibition? While we are familiar with the vulnerabilities of newspaper generally, we are not sure how stable the media will be under exhibition conditions. The exhibition environment is very stable and the newspaper is subjected to low levels of light. While light level is low, with no UV, and the time is restricted, we are not sure how much of an effect this limited light exposure will have on the media.

In order to get a better understanding of how the media will fair under exhibition conditions, we will be monitoring this item closely. To do this, we are measuring the colour by using simple colorimetry. This is completed with 'Lab*' colour measurements which is a method of representing colour using numerical values, in a similar way to the more familiar RGB or CMYK systems. One of the particular advantages of the Lab* system is that it is based on the way in which the human eye and brain observe colours and determine differences between colours. 'L' represents lightness, from 0 (pure black) to 100 (pure white), while 'a' measures the green-red axis (negative values are green and positive values, red) and 'b' measures the blue-yellow axis (negative values are blue and positive values, yellow). The system is capable of detecting colour changes smaller than the human eye can observe, and so gives us another tool to help us provide the best possible stewardship for the items in our collection.

Figure 2: Front page of the Daily Mirror with areas marked in yellow indicating where colour measurements were taken.

Highlighted in the image above are the areas where the colours were measured. The same areas will be re-measured at the end of the exhibition. This will detect any colour changes that have happened (hopefully none) and will inform the future display limitations of this item and for other similar contemporary newspapers.

Item 2. Add MS 88899/6/13:  Greenham fence wire from the Angela Carter archive

Vulnerability: highlighter ink loses colour under light exposure

This item is a piece of wire cut from the perimeter fence of RAF Greenham Common Airbase during anti-nuclear protests by the Women's Peace Camp and sent to the novelist Angela Carter who was against nuclear weapons. It was attached to a record card through two punched holes in the centre with typed notes above and below the wire.

Figure 3: Add MS 88899/6/13:  Greenham fence wire from the Angela Carter archive with highlighted typed message.

Although the item itself is in good condition, highlighter pen was used over the top of the typed message. Highlighter pens contain fluorescent colours which are notoriously light sensitive; they will not retain their colour over extended periods of light exposure. For this reason, we will be displaying this item at our exhibition under low light levels but we will also be limiting future display in order to preserve the bright colour.

At the British Library we aim to make everything as accessible as possible so that everyone can enjoy the collection and see the items in their original condition. However, in order to preserve the collection some items do need to be restricted for various reasons, such as fragile condition, or in these cases, to limit their light exposure and preserve the bright colours for future researchers to see.  Although this means that some items can only be able to be exhibited for short periods, there are alternative solutions for display. For items that were mass produced or have multiple copies, it is possible that a replacement can be found. When an item is unique or other copies are not available, we can suggest a high-quality facsimile be made, this way the viewer can see the uninterrupted exhibition story. In this way, we can maintain the integrity of our collection for as long as possible, as well as finding ways for everyone to enjoy it in the meantime.

Fortunately, both original items will be displayed in ‘Unfinished Business: The Fight for women’s Rights’.

Learning to Communicate: Before and After Lockdown

Samantha Cawson, Digitisation Conservator

The conservation profession takes skills sharing seriously and so the need to open up channels of communication is essential. This is especially true of The British Library’s Centre for Conservation (BLCC), which has collaborated with institutions all over the world, most recently with China and Palestine. But locally, the BLCC has Deaf members of staff and runs a very popular programme of British Sign Language and audio descriptive tours.  These tours are a great way for our visitors to enjoy our collection items and to get an understanding of the work that goes into preserving them; providing a unique opportunity to ask questions and to sometimes handle conservation tools and materials.

Before

Back in February we invited VocalEyes to the BLCC to run a two-day audio description training workshop in order for our tour guides to gain greater self-confidence and to really perfect their presenting skills for our blind and partially sighted (BPSP) visitors. The training was excellent, and covered topics such as visual awareness training, guiding techniques, guide dog etiquette, and an introduction to Description.

One of the practical exercises was to consider some of the challenges that arise when describing spaces, objects and techniques.  We gave individual presentations to the rest of the group who listened with their eyes closed, exploring terms and vocabulary to get a better sense of how the Tours and BLCC experiences might be received.  This brought up some interesting findings. The first was that it isn’t always obvious what something is just by naming it. This was the case when I began talking about my trusty Teflon bone-folder (pictured and described below). I began by describing the material and size, however didn’t clarify why it was called a bone-folder, which to someone who has never seen or used one, the name itself sounds rather gruesome. It was suggested that this tool required further explanation; for some practical items description becomes easier to comprehend if you include what it is used for, how it works and perhaps a little historical context…something I’ll take into account next time!

A hand is holding a white teflon bone-folder. In the background there is an 18th century manuscript.

Figure 1: This is my Teflon bone folder. I use it to flatten my repairs as it doesn’t burnish or stick to my repair tissue. Original bone folders would’ve been made using cattle bone, hence the name, and is used by bookbinders and conservators for making strong sharp creases in paper. Both styles are used within the studio today and are considered a must have tool. You see, not so grim with a little additional information!

Another interesting topic discussed is how to describe colour. Some blind or partially sighted people are born with some sight, and will retain some memory of colour. Many will be able to see colours and shapes; some will have central or peripheral vision. Even those who were born blind are likely to understand the cultural significance of colour, and so during our training we were encouraged to embrace it within our descriptions, as well as to use a vivid, varied and memorable vocabulary in general. For instance, red may signify passion, richness or heat. Green might indicate freshness, jealousy or decay. This topic made me rather nervous at first, however over time I’ve enjoyed the challenge of creating interesting colour descriptions, which can really bring an object to life. I’m now excited to try and describe the pigments and pages of the library’s collection, some of which are still so vivid and exciting even after hundreds of years!  I’ve included a photograph of a particularly colourful illuminated manuscript which was part of the Pre-1200 digitisation project. How would you describe the colours? They remind me of a bag of mouth-watering sweets!

Figure 2: Add MS 46487 Digitised as part of the Pre-1200 project.

Another area of the training that I was looking forward to was identifying objects which could be handled and passed around the tour group, allowing someone to get a better understanding of the weight, texture and shape of something being discussed. We explored a variety of different possibilities that could be utilised. Here are a few examples:

Japanese Repair Tissues

Japanese repair tissue comes in many different weights and textures, which a conservator will choose accordingly to be as sympathetic to the original weight and look of the damage area being treated. Over the years I have accumulated a scrap box full of tissue. In the future I hope it will be a great resource to pass around a group, whilst explaining why and how we use them!

A hand holds a very fine piece of Japanese tissue. It is so thin and delicate that the hand is fully visible through the matrix of the tissue.

Figure 4: You can just about feel the texture of this very fine kozo tissue!

Finishing Tools

Another great example presented itself during a gold tooling demonstration. This experience not only has the benefit of visitors being able to hold and feel the weight and shape of a finishing tool (and we have so many exquisite examples of them!) but also provides the smells of tools being heated, and the great sizzling sound that identifies when the tool is hot enough to be used. This made for an excellent multi-sensory experience.

A hand holds a heavy metal finishing tool. The tool has the words British Library in a large font type fitted within it. The tool looks well used.

Figure 5: A finishing tool (not heated!).

Binding Examples

And of course a British Library conservation tour wouldn’t be complete without describing different binding styles. We have various binding examples specifically made to present the different sewing techniques, supports and materials utilised when creating a book. It’s a great resource to pass around a group as the ridges and materials of the sewing structure can be easily felt and identified; A great tool for most tours, and a way to appreciate the behind the scenes structure of a book.

Figure 6: A binding with examples of sewing on a variety of tapes and cords that could be used to construct a volume.

On the whole this workshop was a great learning experience. It provided us with new knowledge and confidence, and a greater sense of understanding of how important our presentation skills are to perform a coherent and pleasurable experience for all. But honestly, this course taught me how to describe and achieve the ‘WOW factor’ when bringing to life our beautiful and interesting collections, as well as giving a sense of the passion and expertise that the staff have at the BLCC.

After

One effect of the Covid19 lockdown has been the increased awareness of how important communication is to our well-being. For me and others this has been an interesting and sometimes creative process, as well as highlighting how communication needs to be responsive and inclusive. Having just completed the VocalEyes training and with an unknown amount of time working from home stretched out before me, I decided to continue working on my communication skills and began an online British Sign Language (BSL) course.

A laptop is on a small table in a working from home environment. The laptop screen shows a BSL teacher signing the word 'librarian'. Next to the laptop are two small boxes labelled 'BSL test cards'.

Figure 7: First things first, how to sign ‘library’!

The course covered a whole range of topics such as greetings, numbers, rooms and furniture in the home, colours, weather, travel and jobs. Despite this I still have a long way to go before having a fully coherent conversation using BSL with Deaf colleagues in the conservation studio, or with Deaf and hard of hearing tour visitors. But as the library staff slowly begins to occupy our sites, I look forward to being able to continue the learning process through informal everyday practice (perhaps I’ll even learn how to sign bone-folder!), and hopefully once our tour programme resumes I can put all of these new communication skills to the test!

Disaster Response Plans during COVID-19

The Conservation Department has a well-established emergency response system with Salvage Teams at both our London and West Yorkshire sites. Team members are on a callout rota and will work alongside other colleagues if we have an incident that threatens our collections.

On 23rd March this year, The UK Government announced a nationwide lockdown in response to COVID-19. We, like many others in the sector, had to re-evaluate our underlying assumptions about how we would respond to incidents affecting our collections. Countrywide we were now discouraged from travelling and asked to remain at home.

We are fortunate that our colleagues in the Estates, Health and Safety and Security teams have continued to work through lockdown, keeping our buildings and collections safe. This reduces the likelihood that the Salvage Team would need to be called out. However, we needed to make sure we understood when, and how, we could effectively respond if either Team were required.

Reviewing procedures

This meant we had to review our procedures in the midst of an unfolding situation. We had limited guidance and prior experience to refer to, and so worked methodically one step at a time. Firstly, we clarified what we were permitted to do under the lockdown restrictions and then considered what changes we needed to make to our procedures. The situation meant that we had to be flexible and we realised that any updates made could be subject to further change at a later stage.

Secondly, we needed to communicate any changes to the Salvage Team and other stakeholders, most of whom were now at home and not necessarily easily contactable.

Close up image of text on page
The aim was to produce clear updates to existing procedures

Team safety

Our primary consideration was the safety of the Salvage Team and other colleagues. We already have risk assessments covering normal salvage operations, so my colleague Emily Watts (Collection Care North Manager) and I began by drafting a COVID-19 specific health and safety risk assessment. The risk assessment covered all aspects of the response, from travel to safe working on site. Considerations included: Under what circumstances could the team travel? Were usual travel methods advisable? Were there personal considerations which meant that people preferred not to be on call at this time? 

Any changes that we made also needed to reflect site differences. For example, in West Yorkshire, most people drive while in London, the majority of the team is reliant on public transport.

Secondly, while we always consider the option of providing advice without being on site, we worked through this in more detail to reduce further the likelihood that anyone would be needed on site. If there was a need to attend, could team members arrange to arrive at the point when they were needed? What practical help could we provide remotely and what did we need to be on site to do?

Risks to collection

At the same time, I was taking part in a separate exercise to assess risks to collections during this period. It is natural to assume that while buildings are closed, risks also increase. However, while some may increase, others reduce. The risk assessment evaluated how the picture had changed and identified any increased risks. The outcomes enabled us to identify any mitigation that was needed, for example, regular on-site checks or closer liaison with colleagues who were on site.

Briefing notes communicated the risk assessment outcomes to the Salvage Team. We also briefed our key stakeholders; this ensured that there was a common understanding of the measures in place should there be an incident during this period.

As time has moved on, the lockdown has eased. We have started to reoccupy and open our buildings, and the risk assessment - as a living document - can be revisited and updated.

Practical salvage operations

Once on-site, we needed to consider how the Team could work safely. We needed to think about how the requirement for social distancing could be incorporated when, by its nature, salvage operations rely on close physical working with colleagues.

We have a range of PPE available to the team, but rather than this being selected in response to the incident, we now ask that people don specific items from their arrival on site. In terms of revised procedures, we want to maintain flexibility and not be too prescriptive. We are therefore encouraging Salvage Team members to plan the response carefully to limit the need for close working wherever possible. The Team have been encouraged to raise issues and, ultimately, told to cease operations if they have concerns.

Small adjustments to workflows can be made to ensure social distancing, but there is a knock-on impact. For example, we can minimise activities that do require people to work together closely, such as sheeting up with plastic. We can encourage the use of tools, such as trolleys, rather than passing items from person to person or moving them in pairs. However, we need to accept that this will mean that working methods are less efficient and so could take longer. Team members may also need to rotate more frequently and work shorter shifts, and have more breaks.

By contrast, working remotely, we have realised that video calling software creates more options to provide an immediate off-site response or to have a hybrid response with some team members on-site and others providing assistance from home.

Responding to emergencies

By working out what the significant risks were, and combining this with the need to ensure staff safety, we could then look at how this would affect our response.

As an example, our system is based on us using a series of pool phones which contain our salvage manual in a set of small files. This structure enables the user to navigate to the content that they want rather than wading through a long document to find the relevant section. Each week, those on-call pick up their allocated salvage phone and then return it at the end of their duty week. Now the phones were with those who last used them with no mechanism to swap them between us.

A priority for me was to ensure that everyone still had this information in some form when they were on-call. Provided as long-form documents, this reinforced how well the small bite-size files works. I'm currently working with our IT department to investigate options to switch from using the pool phones to using secure collaborative tools. These can be accessed on a range of devices, ensuring easier access to all Salvage Team resources by multiple users. Changing systems also presents an opportunity to save costs on handsets and data contracts.

One thing we did maintain was our usual rota system whereby the Team members on-call that week report in by email every Monday morning. However, during the lockdown, we have been using WhatsApp (a group messaging app). Communications go to all team members at once, which means that there is less chance of missing a notification if someone can't do their duty or needs to call out the whole team. Again collaborative working tools provide more sophisticated messaging options which could simplify this further.

Some short term changes to procedures, introduced to cover the lockdown period and early stages of reoccupation, are no longer needed.  However, if the need arose, we could reinstate them. Remote working has also reinforced those temporary procedures that work well which we want to continue to use.

Staying in touch

One of the on-going risks we identified was the challenge of keeping distributed Salvage Team members in contact. Team cohesion is critical; successful incident response depends on everyone working together as a team and supporting each other. Not all team members typically work closely together, and those that do were now physically separated. We have recently recruited three new team members to the London Salvage Team, one of whom had not begun their induction process. It was important to me that they and their colleagues felt supported in this unprecedented situation and so we started to think about how best to do this.

Over the last 18 months, I have completely revised the Salvage Team induction training. One of the new additions is a module around decision-making. This involved looking back at actual incidents to discuss what had occurred, how people were alerted, who did what and how decisions were made. New team members who have completed this fed back that they felt reassured by this and much clearer about their role in an emergency. An outstanding action was for existing Team Members to attend the same session.

We have also been offering individual training exercises, for induction training and general refresher training alongside as group exercises. Feedback from these had been positive as people could complete them at their convenience and own pace. We realised that offering similar activities, to be completed at home, would deliver a double benefit. It was a way of keeping the Salvage Team in contact while also ensuring that their skills and knowledge are maintained.

In the next blog, my colleague Nicole Monjeau will explain more about this training programme and how it has developed into something much more valuable than we'd envisaged.
