Collection Care blog

Use is one of the biggest risks to physical collections in a reference library and so it may be a surprise that the Collection Care department supports the recent introduction of self-service photography into general collection Reading Rooms.

Our approach to collection care is underpinned by a risk-based process whereby we balance the risks to collection items against 10 agents of deterioration (Preventive Conservation and Agents of Deterioration), one of which includes use.

At the British Library where the collection accommodates 625 km of storage, the simple act of requesting an item, having it delivered and being able to refer to it in a Reading Room can mean that it has been handled by 5 or 6 people as it moves around the building, or even the country if it is stored off-site in Boston Spa, West Yorkshire. Even with careful handling, this level of movement increases wear and tear over time and the potential for damage.

However, we believe there are benefits to the Reader and the Library in allowing photography for personal reference. If items can be photographed at the desk they are moved less, which minimises wear and tear and the risk of accidental damage.

 Every item is unique and requires special care when setting up for photography.

Many items can be used safely in reading rooms, even if they aren’t in perfect condition. We do have a policy of identifying items which are not fit to issue and have used the launch of self-service photography as an opportunity to reinforce this in staff training. For example, collection items should not be issued if they cannot be handled safely without suffering damage, or further damage, or where there is a risk of loss or partial loss to the item because of existing damage.

Once copyright and other restrictions are considered, decisions on what can be photocopied, photographed or scanned are made based on the condition, format and size of the item and the equipment or method being used to produce a copy. Photography using a mobile, compact camera or a tablet can be a safer form of image capture than photocopying, which requires increased handling. Self-service photography also increases the range of items and materials that can be copied safely as there are fewer restrictions on size and weight compared with photocopying and scanning where the maximum copy size is A4 or A3.

There are, however, risks with self-service photography which also need to be considered. Users may be tempted to take more photographs just because they can, regardless of whether they need them for reference. It is noticeable that when taking photographs, collection items are treated more like objects and the focus is often on obtaining a good image rather than considering the item itself. Photography is good at capturing small details or articles but if people want to refer to whole pages the self-service scanner may be a better option. There are also items which will always present challenges because their size, format or condition makes them unsuitable for any copying.

To address these risks we have listed 10 key points to bear in mind when using and copying collection items. These are included in the video below which provides an overview of self-service photography. The video is also available online here.

In the first phase of self-service photography we have concentrated on photographing printed books, newspapers and periodicals and have a produced a short video explaining how book supports can be a useful tool when taking photographs. 

We are now in the process of developing guidelines for the second phase of self-service photography which will extend the service to special collection Reading Rooms where the range of collection formats are more diverse and varied. Again, our starting point is considering the risks and benefits involved in photographing these items and reviewing the collection care videos we produced a few years ago (Collection Care videos).

Two Hebrew manuscripts in their original bindings came to the conservation studio as part of our
conservation program. Both texts contain the work of Abraham bar Hiyya (d. 1136) who was a medieval Spanish philosopher, mathematician and astronomer.

Background history

Little is known about bar Hiyya’s life except that he lived in Barcelona. Although there are points of similarity with other medieval thinkers, his writings contain a mixture of Neoplatonist, Aristotelian and Rabbinic ideas, with original interpretations. He was often quoted by later authorities and accepted as authoritative. There was often no distinction between astronomy and astrology in medieval Spanish or Latin text. Astrology was consulted for such things as births, journeys, business and weddings. Abraham was the foremost scientific authority in Spain at this time and he was a firm believer on this aspect of astrology. Many of the terms invented by Abraham have remained current in scientific and mathematic Hebrew to the present (1).

Besides Bar Hiyya’s Tsurat ha-arets which was copied c. 15th century in a Byzantine style of Hebrew writing (ff. 2r-54v), Or 10721  contains  two additional treatises copied by other scribes in the 15th-16th century. The two other works are Torat emet imun by Zecharia ben Mosheh ha-Kohen ha-Rofe (ff. 1r-1v; poetry), and Sefer ha-osher (Book of wealth) a scientific treatise (ff. 57r-61v).

Right board of Or 10721.

Left board of Or 10721.

 

The first text was written by Abraham bar Hiyya and was one of the first Hebrew texts on cosmography. It is a short review of the ‘lands according to the seven climates’ - the chief source of geographical knowledge among the Jewish community at the time. Abraham bar Hiyya theorised that the Earth was at the very centre of the universe despite conflicting contemporary knowledge. The second text is a translation into rhymes of Bishop Marbod’s text (c.1090) ‘Liber Lapidum’- a tract on the medical and mystical qualities of precious stones. This text also considers astrological principles and the relationship between geology and the positions of heavenly bodies. The third (ff61v-62r) describes the restorative properties of the eagle.

The manuscript is written in iron gall ink and is attributed to a scribe who worked in Italy named Joseph ben Se’adyah Ibn Hayyim.

Or 10538 is a manuscript copied in Italy and dates from approximately the 14th or 15th century. It contains two treaties on astronomy and the Jewish calendar Sefer ha-Ibbur by Abraham bar Hiyya and Sod ha-‘Ivin by Yosef ben Yehudah Hazan.

Right board of Or 10538.

Left board of Or 10538.

This manuscript was copied in Italy approximately around the 14th or 15th century and was censored in the 17th century. Abraham bar Hiyya’s main astronomical work known as Hokhmat ha-hizayon contains two parts; the first part Tsurat ha-arets or ‘Shape of the Earth’, which is included in Or 10721, and the second Heshbon Mahalekhot ha-kokhavim or 'Calculation of the courses of the stars’ which incorporates a whole section on intercalation. The whole work is probably the first exposition of the Ptolomaic system in Hebrew and was the first complete textbook of astronomy in that language. In Or 10538 Abraham further considered the problems of intercalation to enable Jews to observe the festivals on the correct dates (2).

Both volumes contain texts from Abraham bar Hiyya and both have kept their original 14th or 15th century bindings. Even though the binding styles are completely different, they are both unique objects. We decided to take a minimal intervention approach preserving as many of the historic features and characteristics of these manuscripts as possible, and to allow binding features and intricacies individual to these bindings to be visible. Repairs to these volumes would be carried out in-situ, intervening as minimally as possible whilst allowing it to be accessed safely by a guided readership.

Conservation

Or 10721 - There was an increase in book production towards the end of the 15th century when paper became more readily available and also a greater demand for embellishment of finished books as they became more affordable to produce. This meant that binders had to create time-saving methods which led to the adoption of less durable techniques and materials. Despite this, when developing techniques for book conservation today, we can learn a great deal from medieval book structures as their continuing existence is testament to their strong mechanical techniques of production.

When Or 10721 came to conservation it had missing areas to the leather exposing one of the sewing supports, a cracked and abraded surface, and a missing endband. The other endband was present but breaking away from the binding. One sewing support had broken in the gutter at both joints with the boards, which was causing the first and last sections to protrude from the boards (cut flush to the textblock) at the fore-edge.

A number of folios were loose with subsequent tears and crumpling to the edges. Where the vellum pastedowns had come away from the boards a section had torn away and was still adhered to the inner board surface. Rust from the metal bosses had caused burn holes in the first and last few folios, and the volume had surface dirt throughout.

Damage to leather spine: Thread remnants from the tail and head endbands showing damage from use and original lacing into boards.

 

Some of the damage that has occurred over time has exposed otherwise hidden codicological features which are of interest to the scholarship of bindings of this type. Therefore one factor in the treatment of this item was not to hide this evidence.

The treatment aims for this book were:

• To strengthen and stabilise the sewing structure and its supports
• To reconnect and repair the existing endband (head) and replicate its structure (tail)
• To support and reinsert loose folios and repair vellum pastedown
• To consolidate covering leather

The sewing supports were extended using linen thread which was frayed out and adhered to the wooden board. This repair in addition to repairing and reconnecting the endbands to their cores within the boards helped strengthen the opening of the boards and the connection of textblock to binding. It also helped to ease the sections back into the binding and prevent further damage to the paper where it protruded at the fore-edge.

Or 10721 spine after conservation.

Or 10538 is a manuscript written with iron gall ink on parchment with annotations and foliation in graphite. The binding is limp vellum with the double alum-tawed sewing supports laced into the cover and a foredge flap extending from the left cover. Writing is visible over the covering parchment. The binding has been sewn all along on two double alum-tawed supports with thick linen thread. These supports are crossed and laced into the cover in a triangle pattern. Remnants of alum-tawed ties were observed. There are no spine linings or adhesive on the spine which has a natural hollow. Paper labels are found on the spine and left cover.

We don’t know the exact date of the binding but we do know that limp vellum bindings were commonly used in Italy in the 15th century answering to the increased demands of the time. This is a non- adhesive structure, which relies on strong sewing and materials. On the textblock there are indications that it has been resewn: a central sewing hole is not used in the current sewing and there is evidence of a sewing support in the corresponding place on the spine.

The covering parchment was severely damaged. Assessment showed that it was cockled, brittle, gelatinised, and stiff, with overall staining and abrasion. There was severe shrinkage and the foredge flap has been folded inside the left cover. The right cover no longer extends to the foredge of the textblock. Shrinkage resulted in tension which has contributed to loss of covering on the spine; 50% of the spine covering was missing. There were losses to the corners of the left cover and foredge flap joint. Paper labels on the spine were torn, lifting, and had losses. The sewing was in poor condition, with broken kettle stitches in the centre at head and tail.

The treatment aims for this book were:

• To strengthen and stabilise the sewing structure and its supports
• To repair the vellum cover and infill the losses keeping all the original features

The challenge was to repair the cover without disturbing the lacing paths and undoing the knots. The alum-tawed ties were carefully removed from the right board, leaving the knotted alum-tawed ties of the left board untouched. The spine was then carefully repaired using layers of Japanese papers dyed to match the original colour.

Our approach is always trying not to disturb the codicological features as we can not necessarily anticipate what future research may be looking for. It is always the challenge of book conservators to make items accessible to readers while preserving as much as possible. In this case it has been very satisfying to be able to preserve the individual features of these unique items and make them available to researchers. Of course the books still need careful handling, as they are not only the carriers of content but also of the history of the objects and the history of materials and techniques of the time.

With the recent multispectral imaging of the burnt Magna Carta hitting the headlines following our blog post on the 800 year old Magna Carta revealing its secrets, there has been a lot of interest in the conservation work required to protect such items. The so-called “burnt” Magna Carta (Cotton charter xiii 31a) suffered fire damage in Ashburnham House in Westminster on 23 October 1731. This 1215 exemplification formed part of an exquisite library assembled by English antiquarian Sir Robert Cotton during his lifetime (1571-1631). Cotton’s library forms the basis of our collections at the British Library today, and a recent conservation survey of the burnt material has allowed us to categorise items based on their relative condition, enabling us to immediately identify items suitable for digitisation. This has vastly improved our workflow allowing digital access to a wider audience in a shorter time. 

This piece includes material from an article published by Taylor & Francis Group in Journal of the Institute of Conservation on 29 November 2013, available online at: http://www.tandfonline.com/doi/abs/10.1080/19455224.2013.815122#.VFDzZvmsWtB.

The burnt 1215 Magna Carta suffered fire damage and subsequent interventive treatment. The vulnerable wax seal of the charter melted and distorted in the intense heat. 

 

In the Ashburnham House fire a quarter of the manuscripts were either damaged or destroyed in the blaze, and attempts to extinguish it exacerbated that damage. The documents suffered shrinkage and distortion, bindings were carbonised, ink was lost, soot and dirt was ingrained, tide marks formed on the leaves, and parchment (animal skin) gelatinised. Gelatine is the brownish end-product of a rapid degradation of parchment collagen. Remedial work caused further damage with many of the manuscripts broken up and rebound during salvage. Incorrect reassembly impacted on the codicological history of many of the manuscripts. The darkened gelatinous material which formed along the edge of the parchment was trimmed away from some manuscripts. Unidentified fragments were gathered and put into drawers.

The collection was untouched until the establishment of the British Museum in 1753, where over the coming years invasive treatments were recorded. To separate the leaves which had glued together by gelatinisation, about 40 manuscripts were immersed in a hot aqueous solution (likely to be ethanol in water). Incisions along the parchment edges were made to allow the leaves to dry flat under pressure. Despite the efforts, leaves remained brittle and fragile. Inlaying of parchment fragments into paper was completed in 1856, but a huge number of fragments remained loose and unidentified. While the edges of loose fragments were protected by this inlaying method, over time the degradation of materials caused further concern. The brittle fragments were susceptible to break with every page turn, and acidic paper in heavy volumes tended to cockle preventing the volumes from closing.

Cotton Tiberius A. XII. Parchment fragments were attached to paper in the nineteenth century and incisions were cut along the sides to allow the leaves to lay flat.

 

Our conservators surveyed 243 items from the Cotton Collection, including 21 paper manuscripts. Items were graded on their physical, chemical and overall conditions based on an assessment of the state of the binding and parchment substrate, and thus rated for treatment priority.

Pattern of damage where D (High degree of damage) accounts for 61% of the total items examined. From Figure 2 and 5 in The conservation of the burnt Cotton Collection in the Journal of the Institute of Conservation, 2013.

The nineteenth century treatments have been fundamental to the preservation of the Cotton Collection, and many items thought to be lost have since been rediscovered. The condition survey enabled us to quantify the damage and develop a strategy for the long-term preservation of the burnt Cotton Collection. Items identified as being fragile were immediately withdrawn from library use, while research to determine the best methods of stabilising and housing the items was undertaken. The use of analytical techniques such as near-infrared (NIR) spectroscopy for assessing the deterioration or parchment has enabled a better awareness of the nature and condition of these manuscripts. This information has helped to support the choice and realistic scope of conservation methods. In the case of the burnt Cotton Collection, the future project is now directed towards a preservation approach, including digitisiation and multispectral imaging, rather than an interventive conservation one.

Ground-breaking multispectral imaging work of the British Library’s burnt copy of the 1215 Magna Carta has recovered text which has not been read in 250 years.

This work has been completed by British Library conservators and scientists in preparation for next year’s 800th anniversary of the sealing of the Magna Carta. The so-called ‘burnt’ copy of the Magna Carta is one of four original manuscripts from 1215 which survive. In February 2015, the four manuscripts will be brought together for the first time in history for a special 3-day event, which will allow further academic study of them side by side, as well as the once-in-a-lifetime opportunity for 1,215 people to view them together.

Figure 1: Top left: The “Burnt Magna Carta” ready for multispectral imaging. Top right: A real colour image of a section of the charter. Bottom: A processed image of the charter enhanced to reveal text thought to be lost.

The British Library owns two of the original 1215 Magna Carta manuscripts (the other two are held at Lincoln and Salisbury Cathedrals). The story of the ‘Burnt Magna Carta’ (Cotton charter xiii 31a) held in our collections is a truly remarkable one of survival against all the odds. In 1731 it was damaged in the Cotton Library fire, and subsequently staff at the British Museum Library used 19th century techniques to try to flatten and mount it, which has contributed to its current condition today rendering the text very difficult to see.

The multispectral imaging of the burnt Magna Carta was conducted as part of a major project involving the reframing and scientific analysis of all the Magna Carta charters held in our collections ahead of the 2015 anniversary. The Collection Care team provided an initial examination of the original frames to determine their structure and composition. All original mounting materials in contact with the charters were tested using infrared spectroscopy, pH tests, and lignin tests to determine their stability and compatibility with new materials. Once the charters were removed from the frames, near-infrared spectroscopy and high resolution digital microscopy was used to investigate the condition of the ink and parchment as part of the overall condition assessment.

With the frames and glass removed there was a rare opportunity to employ the cutting-edge technique of multispectral imaging enabling us to virtually peel away the layers of damage currently affecting the manuscript.

 
Figure 2: Clockwise from top: Temporary housing is prepared to store the charter when removed from the frame; the original wooden frames are removed to enable access to the charter; the charter is released from the mounting; once the charter is free from the frame it can undergo condition assessment.

Multispectral imaging is a non-destructive, non-invasive imaging technique using different colour lights, including ultra-violet and infrared, to recover faded and lost text. A high-resolution camera is securely mounted directly over the charter, which is then illuminated with LED lights ranging from the ultraviolet at a wavelength of 365 nm, through the visible region, and right up to a wavelength of 1050 nm in the infrared region. The chemical composition of the material in the charter is varied (ink, parchment, etc.), and so reacts differently to the lights. We are able to see, and capture, additional information undetectable by the human eye.

Figure 5: A colour UV image reveals regions of text which are completely faded to the naked eye.

Using this technology and expertise available to us in the 21st century, we are able to preserve the Magna Carta for the next 800 years and present these iconic documents in the best possible condition for visitors who come to see them during the anniversary year.

Multispectral data is still being processed and will be published along with other scientific data collected after the British Library’s exhibition ‘Magna Carta: Law, Liberty, Legacy’, which runs from 13 March – 1 September 2015.

Our next major exhibition ‘Terror and Wonder: The Gothic Imagination’ opening on 3 October 2014 will explore Gothic themes in art, architecture, literature, music, film and fashion. It will look at the impact British Gothic had, particularly in literature, on Europe and North America, and will explore our continuous fascination with the sublime, sinister and the supernatural in human nature – although ever present – first fully explored through the Gothic imagination.

The exhibition will be showcasing some key items from our collection including the first Gothic novel: The Castle of Otranto written by Horace Walpole* and published on Christmas Eve, 1764; hence the exhibition taking place this year on the 250th anniversary of its publication. It is rare that such classic items from our collection find their way to the conservation studio prior to major exhibitions as most such iconic items would have already undergone conservation in the past. I was therefore surprised, but at the same time very excited, when I saw The Castle of Otranto on the list of items requiring preparation for the exhibition.

The leather bound volume of The Castle of Otranto with the original gold tooling on the front board showing Walpole’s coat of arms.

Needless to say, the small leather bound book looked in pristine condition and the only work it
required was minor trimming of the guards (additional strips of paper attached to the spine side leaf edge) at the front of the book. The volume was probably re-backed about 25-30 years ago. The first few folia must have been loose, as they were re-sewn on guards which were left a little bit too long.

 The volume with guards before and after trimming.

Other volumes for the exhibition required more conservation work including: boards, folia or spine
re-attachments, repair to binding edges or corners, and tear repairs to folia within the volumes. In
total, conservation received 35 items from our collection for preparation, and almost half of those
were volumes. For example, Ann Radcliffe’s The Mysteries of Udolpho had a loose front board, while the spine had to be repaired and re-attached on Beardsley’s The Yellow Book.

The British Library has a rich collection of Gothic material, but a number of items, almost double the amount of items requiring conservation, will also be loaned for the exhibition from various museums, galleries, libraries and institutions across the United Kingdom. Conservation will be involved with condition checking prior to the exhibition for some of those items, while others will be checked on arrival. The key loans for the exhibition include paintings, posters, furniture, costume and film. Visitors can look forward to nearly 30 film posters, props from Stanley Kubrick’s film The Shining, photographs and investigative report from a haunted rectory, as well as a rare Limoges enamel casket belonging to Horace Walpole which depicts the murder of Thomas Becket.

On a personal level, I was very pleased to be asked to mount an engraving showing the view of
Strawberry Hill. Strawberry Hill was the eccentric and idiosyncratic home of Horace Walpole built in the Gothic revival style. His home was also the inspiration for his writings; most famously the
setting for The Castle of Otranto.

 The view of Strawberry Hill near Twickenham mounted in cream museum board.

I first visited Strawberry Hill when it was still in the first phase of restoration, and was  fascinated by its history, significance in the development of the architectural style, connection to the Gothic novel and… the papier mâché ceiling! Horace Walpole once famously said that his buildings, like his writings, were made of paper and would be blown away 10 years after his death.** He obviously underestimated both the strength of paper and his writings, not to mention his lasting contribution to the new literary genre and the Gothic Revival in architecture.

The current exhibition will bring the story of Gothic to the present times, showing our enduring and continuous fascination with the romance of the medieval past, as well as the darker side of human nature and the supernatural!

I would like to thank Tanya Kirk and Tim Pye, the curators for the exhibition, for their help with
the blog and the invaluable information provided on the content of the exhibition, as well as
references for the quotations included.

Footnotes:

*Horace Walpole, the youngest son of Britain’s first Prime Minister, was a man of letters, historian,
collector and an influential social commentator and trendsetter of his times.

**Horace Walpole’s letter to his cousin, Henry Conway, on Aug 5 1761: 'My buildings are paper, like my writings, and both will be blown away in ten years after I am dead.' He also expressed a similar sentiment in a letter to Anne Fitzpatrick, Lady Ossory, on Aug 11 1778: 'I am no poet, and my castle is of paper, and my castle and my attachment and I, shall soon vanish and be forgotten together!'

In our last Adopt a Book conservators post, we introduced conservator Kim Mulder who has a special interest in large paper objects. Now, meet book conservator Rick Brown who joined the Library as an apprentice in 1984 and has been involved with the Adopt a Book scheme since it first began.

I have been working in the conservation department on British Library collection items since September 1984: at the newspaper library in Colindale, at the Bloomsbury bindery (British Museum), on the 6th floor of St Pancras (British Library) and now in the purpose built Centre for Conservation situated at the back of the British Library St Pancras site.

I was taken on under an apprenticeship scheme which consisted of being taught by a journeyman (mentor) and attending a day release City and Guilds course at the Elephant and Castle London College of Printing.

In those days there was no such thing as a book conservator as the role was split into four disciplines; sewing, paper conservation, binding/box making and finishing (gold leaf lettering).

I was extremely lucky to be trained at the British Library (British Museum) at that time as the conservators, binders and finishers there were some of the most skilled in the profession. I have nothing but good memories of working with these people and I owe them so much.

We now undertake a minimal intervention approach; we conserve and repair just enough without removing any features of the item’s historical past. To do this you need to be fully skilled in all disciplines. Alongside scheduled work to treat items, we also undertake a programme of running repairs where items which have been identified as needing minor repairs come into the studio and are repaired in less than ten hours. One of the running repair items I’ve worked on is The Secret Garden (1911).

Watch Rick making repairs to The Secret Garden in this video about supporting the Library’s conservation work.

I have been involved in the Adopt a Book scheme since it first began; where a group of school children came to the Bloomsbury bindery for a visit and after seeing the work that was being carried out suggested that they fundraise for a particular book to be conserved. It was thought to be such a good concept that it was advertised as a gift idea. I remember seeing adverts for Adopt a Book on tube stations and inside tube train carriages. Books were conserved for the Adopt a Book scheme by all conservators until it was decided in 1998 to have a dedicated Adopt a Book team, for which I became manager.

Adopt a Book works in a different way now to when it started. The program now supports the work of our conservators rather than funding for an individual book to be repaired. This is a more sensible approach as it helps the future of conservation at the British Library and manages to conserve more items in the process.

Rick working on one of the maps in our collection.

From a memorial to a loved one who read a particular book to their children, to readers who used a book consistently whilst researching at the Library; I am still touched by some of the stories I hear for the reasons why people adopt books.

The Collection Care blog is a year old this week! It has been a wonderful 12 months for the blog, due largely to you, our loyal readers. Since fluid, food and flames are generally considered our nemeses, we'll hold off on the champagne and birthday cake. Instead, to celebrate, we have compiled a list of the top ten most popular posts. Boy, do we know how to party!

10. A-a-a-choo! Collection Care's Dust Busters: In this post we shared the work of our dust busting team who monitor dust in order to protect our collections. We took a look at what exactly dust is, and how to balance the benefits and risk of dust minimisation programs. Who you gonna call? Collection Care! 

9. Goldfinisher: He's the man, the man with the Midas Touch: Doug Mitchell is our book conservator and gold finisher extraordinaire. Doug demonstrated the blind tooling technique and showed us the variety of tools involved in the process.

8. Sea Snails & Purple Parchment: Did you know that the colour purple found in many of our manuscripts comes from sea snails? The snails are essentially "milked" to extract a gland secretion in a very labour intensive process. 

7. A Guide to BL book stamps: You've seen them on our collections and online, but what do they mean? Library stamps are generally divided into four types according to when they were in use, ranging from 1753 to the present day.

6. Digitisation as a preservation tool; some considerations: This post by Qatar Project conservator Flavio Marzo confronted the growing public expectation for online access. Marzo challenged the conservation community to use mass digitisation as an opportunity for the long term preservation of historical items and their features.

5. The Bookie Monster: attack of the creepy crawlies!: Here we delved into the underworld of pesky pests who seek to eat their way through our collections. We identified some of the primary culprits and showed examples of damage to look out for.

4. Cleaning and rehanging the Kitaj tapestry: What happens when creepy crawlies do successfully attack? This year we had to don our hard hats to remove the enormous R.B. Kitaj Tapestry If not, not from the St Pancras Entrance Hall for conservation cleaning. The tapestry was hoovered and frozen to remove all pests and surface dust before rehanging in the hall. It was a major operation and a complete success. We even made a time-lapse video!

3. Fail to prepare for digitisation, prepare to fail at digitising!: Digitisation is much more than just taking a picture. With mass digitisation projects being announced every month, we shared what we've learned when it comes to preparation. We listed five main outcomes of pre-digitisation checks, which highlighted the potential risks in each case.

2. Books depicted in art: Being surrounded by books everyday is all part of the day job for us here in Collection Care. As you can imagine, seeing books in paintings can be quite thrilling. In this lavishly illustrated post we saw that some historical paintings contain a wealth of information about bindings that were not well-documented in the trade.

1. Under the Microscope with the Lindisfarne Gospels: Finally, in our most popular post, we shared microscopy images of the Lindisfarne Gospels collected by our team during a condition assessment. At up to 200 times magnification the medieval artistry and attention to detail blew us all away.

Many thanks to all our readers from the Collection Care team. As ever, we are truly grateful for your following and are always keen to hear from you. Do let us know if there are any topics you'd like to read about, and don't forget you can subscribe to the blog at the top of this page, and follow us on Twitter: @BL_CollCare

When items from the Library’s collection (and from other institutions) are exhibited to the public, it is important to ensure that none of the other materials used as part of the display (fabrics, foams, plastics etc.) will cause problems, for example by becoming acidic or releasing reactive gases as they age. As a result we work closely with the British Library’s Exhibitions Department to test the stability and compatibility of any new materials that are under consideration for use.

The ‘Oddy Test’ is an accelerated corrosion test developed by conservation scientist Andrew Oddy at the British Museum in 1973. It is used to predict potential off-gassing from new materials to determine whether they are safe to use with collection items in an enclosed space. The suitability and compatibility of a material coming into close contact with a collection item is predicted by measuring (semi-quantitatively) the extent to which a new material will release harmful volatiles over a long period. If enclosed in a small space, volatile components such as organic acids, solvents, oxidants and sulphur compounds may reach dangerous levels of concentration capable of damaging objects through corrosion of metals or degradation of organic matter.

Fabrics Testing

 Fabrics for testing

Enclosed spaces could include showcases for exhibition, storage crates, contained shelving or individual item storage boxes. It is important to test all of the materials that the collection item will be exposed to in order to ensure the item is not at risk of damage. For example in the case of a new storage box for loan transport we would test a small sample (approximately 1g) of the board, fabric, adhesives and foam which make up the box.

Method

The original Oddy Test has since been developed into the 'three-in-one' method, but the theory is the same. In the original setup samples of the material in question are placed into three separate test tubes. Approximately 1 ml of de-ionised water is placed in a vial inside each of the test tubes to maintain a high relative humidity. In the first test tube a clean metal token of copper (Cu) is suspended over the sample on polyester thread, in the second a token of silver (Ag), and in the third a token of lead (Pb).

The Oddy Test

The test is evaluating the extent to which a new material corrodes these metals, and any alloys containing them. Copper, silver and lead are used because they react to a different set of gaseous pollutants, but results are applicable to all material types. Copper detects chloride, oxide and sulphur compounds, silver detects reduced sulphur compounds and carbonyl sulphides and lead detects organic acids, aldehyde, and acidic gases. Three identical test tubes with metal tokens and de-ionised water are setup as a control.

The containers are sealed up with glass stoppers and secured in place with heat-shrink tubing. To mimic the aging conditions they are placed into a heated oven held at 60 °C. This replicates a ‘natural’ ageing process of approximately 5-6 years. When 28 days have passed the containers are removed from the oven and the tokens are examined. The presence of volatiles is indicated by any corrosion or tarnishing of the tokens. The extent of corrosion gives a rough indication of the level of off-gassing. If the tokens show no signs of corrosion then the material is deemed suitable for use with collection items.

Further Oddy Test developments have seen the 'three-in-one' test where all three metal tokens are placed in the same container over the sample, making sure they are not touching each other or the sample. The interpretation of the results is somewhat subjective given that visual cues such as changes in lustre, colour or texture are used to classify the suitability of the test material for use.

Stability of the materials can be further tested with the use of Image Permanence Institute ‘A/D’ strips. These strips measure the short-term release of volatile organic acids. Oddy testing is just one of several tests that a material must pass before it is accepted for use near a collection item. For example infrared spectroscopy allows us to determine the chemical composition of the sample, enabling us to predict its likely behaviour. Surface pH measurements give an indication of the way in which the acidity of the bulk sample changes over time.

By working with conservators and the Exhibitions Department in this way, we help to ensure that the Library’s collection can not only be displayed in the best possible manner, but that it is also preserved for future generations.
