This article outlines the investigation into the item ‘Swarbreck’s Sketches in Scotland’ and where the item belongs.  

On a smoky day in August 2023, Swarbreck’s Sketches in Scotland appeared on shelf 11B in the Qatar Storage Area. Nobody knew where this item came from or how it came to be on the 6th floor. The item had no content and was merely a front and back cover. Why was it in this storage area? Who put it there? Was the ghost of Swarbreck haunting the 6th floor?

This is the tale of how the mystery of Swarbeck’s Sketches in Scotland was resolved.

Following the smoke incident on the 6th floor on Tuesday 15th August 2023, all items on the floor were moved into the Qatar Storage Area and audited by the Qatar Project Library Collection Assistant’s. when it was safe to re-enter the office, the QPLCAs promptly conducted an audit of the Qatar Storage area, when a mysterious discovery was made, an item called ‘Swarbreck’s Sketches in Scotland’ which did not have a ticket, used for tracking items within the library. The item had no content and was simply the front and back cover. The LCAs first made enquiries with project colleagues enquiring within the project, it was concluded that nobody within the project knew where the item had come from or why it was in the office. No concrete evidence could be established as to how this item came to be on the 6th floor. How were they ever going to find out where it came from?

The first step in investigating this item and how to return it to the correct department was researching the item in consulting the online catalogue and IAMS. A breakthrough was made- it was found that an item with the name ‘Sketches in Scotland’ by S.D. Swarbreck on the temporary catalogue had two potential shelfmark entries- ‘1780.c.1’ and ‘X 1237’. ‘1780.c.1’ could have been stored in any of the 625km of shelves¹ within the library, however ‘X 1237’ was clearly a map which narrowed the search to only 4.5 million maps².

Img. 3: X 1237- Deleted

Upon searching for X 1237 it was found that the item did not exist. In the paper catalogues in the Upper Ground Maps storage, the record for the item said, ‘Not found- entry deleted’. It was a dead end. These paper catalogues contain information from ‘A catalogue of manuscript and printed reports, field books, memoirs, maps, etc., of the Indian Surveys, deposited in the map room of the India office’ originally compiled by Clements Markham in 1878 and so was likely out of date.

However, the item 1780.c.1 was found in basement 2 of the library. The item was similar in size to the front and back covers in the Qatar storage area and the title matched. It was the breakthrough they had been waiting for...

Through research and enquiring around the library, it was concluded that ‘Printed Heritage’ was the department they needed to interview for Swarbreck. Helen Peden, Lead Curator of Printed Heritage, met the LCAs and assessed the item, concluding that it belonged to the Printed Heritage Office. The covers could finally be returned to where they belonged.   

The final decision with what to do with this item was made- for the old front and back covers (found in the Qatar Project Storage Area) to be placed in an envelope with the current item, 1780.c.1, so that the items could be stored together.   

This tale is a clear example of the variety of resources in the British Library Collection and how much items move around the library. It also shows how easily an item can be lost and the importance of tracking collection items.  

Where did the item come from?  

We believe that the item may have been conserved on the 6th floor when Conservation was operating here (before the Qatar Project) however this was over 12 years ago.  

It was also theorized that it may have been relocated from one of the offices on the other side of the 6th floor from the Qatar Project, during the smoke incident.  

We do not know for certain where the item was stored on the 6th floor or how it came to be on the 6th floor. 

Who was Swarbreck?   

Samuel Dukinfield Swarbreck (fl. 1830-1865) was a painter of landscapes and townscapes and was well known for his sketches of Scotland. In 1839, he issued a folio set of 26 tinted lithographs under the title Sketches in Scotland, drawn on stone from Nature. These prints show different areas of Scotland, including busy streets in Edinburgh and the Scottish Highlands. These works represented a romantic visual representation of Scotland, with views of idyllic countryside and cityscapes.  

Swarbreck exhibited at the Royal Academy in the 1850s and 1860, exhibiting over eight artworks. His most famous work, The Bedroom of Mary, Queen of Scots, Holyrood Palace: showing the anteroom where Rizzio was dragged and murdered, and the secret staircase by which the conspirators entered was exhibited in 1856³. His work is represented in institutions including the City of Edinburgh Collection, Culzean Castle and Manchester Art Gallery.

Last month we launched a fundraising appeal to raise vital funds for our conservation work. Discover how donations will support the work of people like Roger, one of our specialist conservators.

What does a day in your life look like, Roger?

There are over 170 million collection items at the Library so each day is different and no books are the same every week.

I usually spend five hours a day working on items. The rest of my time includes discussing solutions to solve problems on items and attending Topic Talks where my colleagues in conservation share their skills or give presentations.

I love the variation. For example, I recently started writing condition reports for exhibition items that go on display. This includes some photography and making notes of existing wear and tear on books.

How long does it take to conserve a book?

Something like rebinding a book could take 45 hours or more. This includes removing old glue from the spine, pulling out text block sections and resewing the binding. Any extra work like washing acidic paper, a type of paper which was widely used from the 1900s which turns yellow and brittle over time, adds hours of work. The greater the damage is on a book, the more work is involved.

What’s the biggest transformation you’ve made on a collection item?

These are my favourite pictures of my bookbinding work. It’s a Sale Catalogue by Southgate Auction Rooms from the 1800s which was in a very poor condition with both covers detached from the pages. The first two pictures show the item before treatment and the third shows the reattached spine and binding.

I’ve done many transformations on books, large and small, and these pictures show how a damaged item can get a new lease of life through conservation.

What are some of the challenges you face in conserving an item?

As a conservator, you need to be patient. I remember working on a newspaper with very weak acidic papers. You can see how brittle papers like these are in the picture of the fragments below.

I had to be careful to handle the item as when I lifted it, part of the newspaper cracked and fell off. I managed to restore it with Japanese tissue and wheat starch paste to re-enforce the strength of the paper. This treatment should extend the life of these newspapers so that they can be safely handled, which would not be possible without intervention.

What’s an area you’d love to learn more about?

Cutting tools are really important for bookbinding. It’s important that they remain sharp so that you can cut and trim paper with precision. A book looks much better with nice trimming so I would love to learn more about knife and scissor sharpening, like how to sharpen French paring knives in the correct way.

What’s your favourite thing about working in conservation?

That you are always learning. Every day, I’m gaining more knowledge about all kinds of bookbinding materials and the different skills involved in bringing items back to life.

How to support Roger’s work

As a charity, donations help us make the most of our conservators’ incredible knowledge and talent for their craft.

By making a gift today, you could help Roger and his colleagues deepen their expertise through specialist training, helping them find new ways of bringing books back to life.

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 20^th 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] 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] 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 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.

Marya Muzart, Digitisation Conservator, International Dunhuang Project

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 2: Recto before treatment.

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. 

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.

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 28^th 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.

Figure 1: Controversial front page of the Daily Mirror on Tuesday 28^th March 2017 (NEWS.REG170)

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’.

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.

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.

It was important to ensure the Salvage Team felt safe if they were called out

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.

The benefits of short electronic files were clear when compared with long form documents

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.

A presentation on decision-making is a key part of the Salvage Team induction process

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.

What do you do when something unexpected happens? When out of the blue something quite big lands in your hands? This is something that we can all too easily relate to today.

Back in March 2019 this is the question I faced when 85 rolls arrived at the Library in need of cleaning, repair, housing, cataloguing and a new storage space. 85 items are a lot of work to fit into an already busy schedule and it had a significant impact on my work over the following 12 months.

Picture 1: The rolls when they arrived in the BLCC (British Library Centre for Conservation)

The story concerns rolls that were previously stored in King’s Library at the British Museum, the gallery today known as the Enlightenment gallery. The British Library’s dedicated building in St Pancras opened in 1997 when the main collection was moved, which was followed by the King’s Library Collection in 1998. These rolls however only came to the British Library last year.

When the British Library’s collections were still at the British Museum, the rolled items were locked in secure cupboards underneath the display cases in the King’s Library. This included some rolls from the King’s Library’s collection but also many other rolls from the general collection which were stored with them because of their size.

In the 1970s, the King’s Library Gallery was re-furbished with new display cases. Then, after almost 50 years, one of the old cases that had been in storage was forced open to reveal a previously forgotten compartment. Inside, they found dozens of rolled sheets formerly stored in the King’s Library, long since established as ‘historically mislaid’ by curators at the British Library. The Museum hastily handed them over.

On arrival they were brought to the Conservation Centre for an initial condition assessment. Once it was confirmed that there were no signs of pests or mould I conducted a more detailed assessment of the conservation needs of each roll, liaising closely with the Cataloguer and Curators who would update the details in the catalogue.

I started by assessing each roll individually, recording any conservation treatment required for their safe storage and handling. A spreadsheet was provided with the rolls where I had planned to record for each item whether it needed:

1. Surface cleaning
2. Repair
3. The rolled dimensions, in order to make a storage box.

It quickly became apparent that it would not be so straightforward. Firstly, many rolls had other elements that would complicate their repair, boxing and storage, such as: loose or attached labels (paper or parchment), textile ties (of various colours and conditions) and wooden rods (in varying conditions) that also needed to be recorded. But more problematic were the shelfmarks; many weren’t easy to read, some rolls shared the same shelfmark, others were so similar it was hard to tell the difference, and some had shelfmarks that were not listed on the spreadsheet. This made locating each roll in the spreadsheet very difficult, I had to use any other information I could find to identify what was what.

Picture 3: Example from spreadsheet of items with similar shelfmarks

As these rolls already belong to the British Library’s collection there should already have been a record of each roll in ABRS (Automated Book Requesting System). However, the Cataloguer had a difficult time locating the rolls on the catalogue because of the unclear shelfmarks. Using all the information he had – date, title, source and stamp, and any other information on the physical items – he searched the various catalogues, electronic and printed ones, and eventually found 53 of the rolls in the catalogue, all of which had been marked as ‘mislaid’. Of the remaining ones, 14 more were found in a manuscript location list drawn up in the 1970s in a notebook labelled 'Location List [Rolls] King's Library', the location being 'housed in 1st case in Gallery', referring to the British Museum’s Enlightenment gallery. Finally, the Cataloguer suggested new shelfmarks, which will be used to label the rolls’ storage boxes.

The conservation was straightforward, but lengthy. Every roll had a thick layer of dust that needed to be cleaned, this was done with a chemical sponge, gently lifting the surface dirt. Some also needed repair as they were damaged along the edges, these were repaired from the back of the roll using Japanese tissue paper and wheat starch paste. A few in poorer condition also needed repair from the front using a thinner tissue that added the necessary strength and remained discrete. Once complete, the rolls were put into their custom-made box and sent to their new storage place where they are now accessible for any interested researcher to marvel over.

To finish I will share why this unexpected arrival was such an exciting one. The collection is of significant value and includes items such as:

• The ‘Description of the Jousts held at Westminster 13th Feb 1510 to celebrate the birth of Prince Henry’, a unique printed and hand-coloured copy of the original painting on paper belonging to the College of Arms, this roll being the longest of the 85, measuring over 5m long.
• Prints from the famous 18^th century Italian printer, Piranesi, such as the Colonna Trojana, unique in this roll format. This is one of the rolls belonging to the King’s Library collection.
• Various genealogies such as ‘Heroldt - pedigree of Germanic kings etc’, a very large roll depicting each family members with their coat of arms and with detailed images of German cities in the background.

Un-expected things happen. I learnt through this project that we can (and should) plan for the future and do this well to make our work as efficient as possible, but it’s nothing new that many things remain out of our sight and we have to learn to be flexible and adapt as these come along.

I really enjoyed being part of this project of organising (and doing some of) the cleaning, repairing and housing of this amazing roll collection from the King’s Library. It was exciting to be part of this long story, have a role in making this ‘once lost but now found’ collection available for many others to enjoy.

Marya Muzart, Digitisation Conservator International Dunhuang Project

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 4^th to the beginning of the 11^th 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.3455, and introduces the approach taken when we come across a scroll with historical repairs which are causing damage, but which we do not want to permanently separate from the scroll.

Picture 1: Recto before treatment.

Picture 2: Verso before treatment.

Or.8210/S.3455 is an 8-metre-long scroll with many historical repairs (we know that these repairs predate or date back to the beginning of the 11^th century due to the provenance of the items in this collection). Carrying out repairs on damaged scrolls was a common practice in Buddhist monasteries, so we frequently come across historical repairs in the form of paper patches not only in the Lotus Sutra Project, but the Stein collection as a whole.[1]

These repairs are present throughout the scroll in varying sizes, however the two large historical repairs on the 1^st and 2^nd panel were the most challenging ones in terms of treatment. As we can see from the images above, the historical repairs in combination with the adhesive used were causing extreme distortion. As a digitisation conservator my aim is to ensure the item can be safely handled during digitisation and to ensure the text is visible and accessible so that high quality images can be taken. Not only was the scroll incredibly vulnerable to any handling, but its condition would have also made it impossible to produce suitable images during digitisation. This is why treatment on this scroll was necessary. 

Examining the scroll before treatment, it was clear that the historical patches needed to be removed in order to flatten the scroll and carry out repairs. Because the scrolls are archaeological artefacts, separating the historical repairs not only runs the risk of disassociation from the original manuscript, but it also takes away from its rich history as an object. This is why we always aim to avoid the permanent separation of any historical repairs from scrolls and I took the decision to reattach the historical repairs as a final stage of treatment.

How detrimental a historical repair can be, is dependent on the paper and the adhesive used. Thick paper and thick adhesive will cause distortions, as we can see in the images above. However, there has been evidence of some historical repairs applied very finely. So each historical repair that we see during the project presents a unique situation and treatment approach.

Picture 3: Verso after removal of historical repairs. Excess adhesive can be seen, which required further removal. 

The first stage of treatment was to remove the historical repairs. After surface cleaning using a cosmetic sponge, gentle humidification was applied. Patience is key here, as I had to work one small area at a time using a micro spatula to slowly lift the historical repairs. It was important to get enough humidification introduced to soften and swell the adhesive for easy removal, but not so much as the paper would become extremely wet. You can see from the image above, once the historical repairs were removed, the dark crusty areas show how thick the adhesive had been applied, which further helps us to understand the distortions and tensions caused by this. The excess adhesive was further removed using the same technique; gentle humidification and a micro spatula. Any adhesive which was removed was kept in small sample bags for possible future analysis.

Once the historical repairs and the majority of excess adhesive was removed, the panels were flattened under boards and weights. When flattening was complete conservation repairs on the scroll were carried out using toned Japanese paper and wheat starch paste. When the conservation on the scroll was completed, it was time to reattach the historical repairs. 

The historical repairs were not reattached fully onto the scroll. Completely pasting down the historical repairs would simply cause the same damage as before. Instead, they were re-attached using some small Japanese paper tabs and wheat starch paste, each tab measures no more than a few millimetres and these are placed at strategic points underneath the repairs to stop any tension and subsequent distortion from occurring. These can easily be removed in the future if necessary, by simply cutting the small Japanese paper tabs, or by introducing gentle moisture to soften the wheat starch paste. It is important to note that the scroll spends the majority of its life rolled up, so the historical repairs were reattached whilst the scroll was rolled up. If they had been re-attached whilst flat there would be much tension occurring once it is rolled up. 

As you can see from the after treatment images, the historical repairs now do not create any tensions or distortions. The scroll can be safely handled and digitised by trained internal staff. By re-attaching the historical repairs, we have successfully avoided the disassociation that would occur from permanently separating the historical repairs from the scroll, therefore losing a part of its history. All in all, the treatment was successful.

Figure 1: IO San 3251 before treatment.

The British Library has a large collection of birch bark manuscripts. This particular manuscript was flagged for conservation because it was requested for digitisation. Unfortunately, due to its condition it was unable to be safely handled.

This manuscript known as The Mahārnava, from Kashmir, was written in Śārada on birch bark and dates from the 19^th Century. The text discusses Hindu religious law (Dharmaśāstra) dealing with practices for removing and healing diseases and bad influences resulting from the deeds in a former life (Karmavipāka).

Figure 2: IO San 3251 front cover.

Figure  3: IO San 3251 back cover.

The text was compiled probably in the 14^th century, and so the text isn’t so uncommon, however this manuscript still has its original limp vellum cover, which makes this example quite unique. The treatment plan for this object needed to fit for purpose, dealing with it more as an object rather than a manuscript that would be requested and used as a book.

Figure 4: IO San 3251 fore edge before treatment.

Made from the bark of birch trees, each page is made of a laminate of birch bark - in this manuscript laminate of pages vary from 3 to 7 layers of birchbark. Layers of birch bark are held together from the natural resins and gum found in the birch bark, however overtime they naturally dry up and lose their adhesive properties, leaving many pages delaminated.

Figure 5: IO San 3251 delamination and tearing.

Almost all pages suffered from large tears and cracks, predominantly following the horizontal grain of the bark. The general fragility from inherent acidic characteristics of birch bark are made worse by the horizontal brown nodes which are more brittle than the surrounding bark due to a higher concentration of lignin, a material that gives off acids as it ages.  

Figure 6: IO San 3251 delamination and tears along nodes.

Figure 7: IO San 3251 old repairs.

The nature of this material and method of production required a much different repair technique than would be employed for paper-based objects. For paper repairs stabilising a tear with a Japanese tissue on the recto or verso is a common technique. However, with this manuscript being made up of a laminate of organic material, it required a more considered approach.  Keeping in mind a balance of tension, and the many layers making up each sheet, a weaving technique was used to weave the repair tissue between the delaminated and cracked areas, where possible.

Figure 8: example of repair options: inserting repair tissue between delaminated layers or weaving repair tissue between tears.

Figure 11: IO San 3251 tear and delamination after treatment.

Methyl cellulose 4% was chosen as the adhesive for its elastic nature, allowing the repairs and original material to flex naturally, and not become stiff as the old repairs.

Pages that had become loose were reattached to each other, weaving the tissue around original sewing to secure them in place.

All repairs have been carried out and now the manuscript is able to be safely handled, pages can be turned without risk of further catching and tearing. Digitisation will be the next step for this manuscript so it will be available to a much wider audience, with minimal disruption to the physical object.

In the late 18^th century, British and European artists such as John Smart and Ozias Humphrey introduced the concept of painting portrait miniatures on ivory to local artists in northern India. By the mid-19^th century, Indian artists also used relatively small ivory discs or sheets to paint topographical views and genre scenes as well. In 2018, the Visual Arts section added to its existing collection of works on ivory, two portrait miniatures reputed to be the infant sons of Wajid Ali Shah (1822-87), the last King of Awadh and date based on stylistic grounds to c. 1840-42.

Portraits of the two young sons of Wajid Ali Shah, the King of Awadh by an unknown Lucknow artist, c. 1840-42. British Library, Add Or 5710-5711.

One of the two portraits show a young child of about 12 months old based on the fact he is pictured being supported by a bolster on the ground and cannot sit up properly. The second portrait displays a slightly older child of no more than 2 years old pictured seated in a European style chair. J.P. Losty (formerly the Head of Visual Arts) suggests that these two sitters were most likely to be the second and third sons of Wajid Ali Shah, as the first-born was deaf and mute and hence passed over. The second son being Falak Qadar ‘a fine-looking boy’ who would die prematurely of smallpox at the age of 11^[1] and the third son being Hamid Ali (1838-74) would become the prince-apparent. Hamid Ali would later visit Britain in 1857, photographed by Leonida Caldesi at an exhibition In Manchester in July 1857^[2].

On acquiring these ivories, the Visual Arts section arranged to have these portraits assessed and obtain proposals for the long-term preservation and storage. The miniatures came to conservation in late 2019 as part of the annual conservation programme.

The objects were both very vulnerable in the present storage box as the ivory substrates were effectively loose in the box and did not come with any ‘accessories’ such as backboards, glass or frame.  Both the watercolour media and the ivory substrate were in a stable condition. However, over time, there was considerable media loss mainly on the edges, probably caused by a change in frame/enclosure and being in close contact with a frame or glass that rubbed against the paint layer. Unsuitable materials such as adhesives and poor quality paper or card used for the framing will have contributed to the discolouration, accretions and staining on the edges.

As part of the treatment proposal, the pair of portraits did not require conservation treatment apart from cleaning prior to their rehousing. New enclosures were built in order to accommodate a very hygroscopic material such as ivory. One of the most common damage to ivory miniatures are cracks caused by a combination of restriction of movement to the ivory support and changes is the relative humidity. Ivory needs room to move within its enclosure; if it warps and the frame or support prevents it from doing so, it will inevitably crack.

One of the miniatures prior to being sealed in enclosure.

The miniatures were hinged on top and bottom edges, then the hinges were threaded through a museum quality cream backboard and a Plastazote base. The hinges were secured onto the back of the Plastazote. The rest of the enclosures were built around the base, allowing space around the edges and between the miniature and the Vibac glazing. Mount backboards with Japanese paper flaps were provided to each miniature, these flaps were used to seal the Plastazote enclosures. The Vibac had to be slotted in place with a flush surround made out of mount-board. This allowed for a window mount to be adhered on the top to finish off the miniatures.

A buckram covered tray was made to measure taking care not to exceed the depth of the prints and drawings reading room drawers.  A Plastozote cut out was fitted in the tray to offer extra protection and prevent movement while being accessed by readers. The board with original inscriptions was mounted and rehoused in a Melinex enclosure, all made to fit the tray and to act as a protective ‘lid’ to the miniatures.

Finished miniatures and their tray.

With the pair of ivories in their new housing, it is now possible to make the works available for consultation to registered readers by appointment.
