In September 2022, I began a yearlong internship at The British Library in the conservation department. Prior to this I studied general conservation at Lincoln University, and whilst I enjoyed learning about all types of materials, once I started treating paper objects I knew that I had found my passion, and hopefully my future career.

My studies took place during the Covid-19 lockdowns, so my access to hands on conservation was limited. Entry-level conservation jobs often require a minimum of two years practical experience post training, so finding this internship felt something like a blessing. During my yearlong internship, I have been learning from expert preventive conservators, object, textile, book and paper conservators in a fully equipped conservation studio. This blog post will give an overview of my time spent during the first six months of my internship, beginning with the Exhibitions and Loans team, and then on the long-term bids team.

Exhibitions and Loans 

The Exhibition and Loans (E&L) team within conservation deal with the treatment and condition checking of objects that have been requested for upcoming exhibitions, either internally at the BL or externally at other lending institutions, including touring exhibitions.

Condition checking and documentation is crucial to the culture of institutions loaning each other objects as record of the exact nature and degree of all damage is important to show that an object has not been further damaged during transit or display. I started on the Exhibitions and Loans team during the install of the Alexander Exhibition, where I was able to watch loan items from other institutions arrive, and to see how different conservators at a variety of institutions described and highlighted different types of damage. I also had the opportunity to assess and record the condition of individual items going out on loan and an entire touring exhibition on its return to the Library. This allowed me to familiarise myself with the specialist vocabulary used in book conservation, the various book structures, and the common types of damage.

I have learnt that putting together an exhibition is a truly collaborative process. During the install many different departments work together to ensure that the final exhibition is educational, contains the most relevant and beautiful objects, is enjoyable for visitors but above all that the objects remain safe, stable and undamaged. The E&L team play a massive role in this: they decide which items are in good enough condition to be displayed, undertake any necessary conservation treatments and decide how best to display objects.

I also worked on the Chinese and British exhibition; I mounted many flat items for display, learning various techniques that ensure each object is displayed at its best whilst being appropriately supported.

In addition to mounting objects for internal exhibitions I also treated items for internal and external exhibitions, focusing on damage that could increase whilst in transit or on display or aesthetic damage to the display opening. The following are examples of items I have treated for exhibitions and loans.

Long-term bids

In the long-term bids team I have been lucky enough to have three different mentors with varied backgrounds leading to their slightly different areas of knowledge and expertise. This has been an amazing way of learning as I get to see a wider range of treatments and processes and different ways of approaching similar problems. I have learnt that there is no ‘one size fits all’ approach to conservation, each book is unique and various materials both deteriorate and respond to repairs differently. I explored which approach suited me best and chose the best method and materials for the treatment of every object. I have been able to learn and develop a wide variety of skills this way: tear repairs on flat works, books and scrolls; many applications for different gels; toning tissue; paring, toning  and consolidating leather; repairing board corners; binding repairs; sewing sections of a text block; sewing endbands; removing spine linings and more.  However, for the purpose of this blog I will detail the treatment of 118.e.5, and how I was able to develop the skills required for each treatment step.

Img. 8: Volume 118.e.5 pre-treatment

The tail endband had become partially detached and the endband and spine were dirty. I began with surface cleaning to improve the appearance and to ensure repair materials would adhere sufficiently.

I attended a gels course run by three British Library conservators where I learnt how to make a variety of gels at different concentrations and experiment with their suggested applications.

Img. 11: Endband during cleaning with Konjac & Xantham

Img. 12: Endband and exposed spine after cleaning

I selected Konjac and Xantham gel to clean the spine and endband by applying it as a poultice, leaving for a few minutes and then removing the poultice, which was very effective. The endband was now ready to be reattached!

I learnt to sew endbands whilst making a sewing model, which furthered my understanding of the structure and purpose of the endband.

Img. 13: Sewing model endband

I learnt to reattach endbands by observing my mentor completing an endband repair to a volume where the head and tail endbands were detaching. This enabled me to take photos and make detailed notes before repairing the other endband, giving me enough confidence to carry out similar treatments more independently in the future.

Img. 14: endband fixed into original position and endband markers mark each

I fixed the endband into its correct position using a piece of Japanese tissue adhered with wheat starch paste before marking the centre of each section I planned to sew through. After the first stitch, I tied a knot on the outer side of the spine to secure the thread.

Img. 15: endband sewn back into original position

I then sewed underneath the endband core, back over the top of the endband and then back through the textblock, with a linen thread that closely matched the original white thread.

Img 16: The repair stitches

Now secured, the next step was to reform the head cap using archival calf leather.

I had no experience working with leather prior to my internship, but have quickly learnt that each leather is different and that paring leather takes a considerable amount of strength! My first attempts at paring leather were thankfully on strips of off-cut leather as they were not pretty, though I’m assured it’s a skill that requires much practice to perfect.

Img 17 : The spine edge and head edge of volume 118.e.5 after treatment

After paring and consolidating the leather, I adhered it to the spine using wheat starch paste.

I loved working on this book, having confidence in my ability to complete each step made me feel like a real, fully-fledged book conservator, and I was really happy with the outcome of the treatment. I am learning more and more by the day and whilst I will be sad to leave the long term bids team, I am excited to join the preventive team before returning to the studio to focus on binding structures. If you’ve found this an interesting read, I will be writing another post detailing my time on future teams so watch this space !

Following part 1 of the Conservation of Maps in the digitisation project: Qatar Foundation Partnership, this second blog post will present the treatments of two maps belonging to the IOR collection of the British Library: IOR/X/10065 and IOR/X/10066. Similar to the maps presented in the first blog post, these maps also have cloth as a secondary support. In these cases, the maps were fragmented and lined on a cloth support which allowed them to be folded (picture 1 & 2). A difference with the first group of maps is that they did not have textile or silk ribbons on the edges.

Picture 1: IOR/X/10065 recto before treatment

Picture 2: Detail of the joints (cloth) that allow the folds of IOR/X/10065

These two items had the same main damage. The substrate, a paper lined with cloth, was broken or weakened in various areas of the joints where the maps used to be folded (picture 3 & 4).

Picture 3: Upper part of the IOR/X/10066 recto before treatment

Picture 4: Detail of IOR/X/10065 with broken joints

 

The paper support on the IOR/X/10066 map is thicker and distorted, with the distortions possibly caused by its large format and the broken joins no longer creating tension (picture 5). On both maps, there were small paper tears and folds around the edges. There were also loose threads due to the fraying of the cloth along the edges (picture 6). The condition of both maps made handling and digitisation very difficult, especially due to their oversize format, IOR/X/10065 measuring 1014x750 mm and IOR/X/10066 1235x1073 mm.

Decision making

The aim of the conservation treatment was to stabilise the items to function in their current role and to ease handling for the next stages of the workflow: cataloguing and digitisation.

For the decision-making process we considered the condition of the maps and their original use, to be folded and unfolded many times when used. In addition, minimal intervention, re-treatability and fit-for-purpose, principles from our guidelines, were taken into account, as well as the 5 hours limit for the treatment of each item.

 

Selecting and preparing materials for treatment

Our treatment proposal was then focused on re-establishing the ability to fold the maps which is convenient for handling and storage. We decided on using a cloth lined with Japanese tissue for the joint repairs, similar to the construction of the maps.

 

Selection of the cloth

A thick Japanese tissue would not be enough to repair areas that are to be folded multiple times. We decided on Aerocotton, a material commonly used by book conservators to reinforce book joints which is a light but strong cloth. The cloth was washed with hot tap water before its use to remove any possible sizing and additives.

 

Selection of the Japanese tissue

We chose an 11g/m² Japanese tissue with kozo fibers, which is strong and thick enough to give support to the cloth and the tear repairs.

 

Lining the Aerocotton

Aerocotton is difficult to cut after washing, (see picture 7). Therefore, it was lined using Japanese tissue and wheat starch paste (WSP). This helps to stiffen the Aerocotton, with the Japanese tissue working as a support to make it easier to handle and to limit frayed edges. The cloth lined with the paper was left to dry on a wooden board similar to a karibari, to ensure it dried with tension (picture 7).

Picture 7: On the left Aerocotton dried after washing and on the right lined Aerocotton with Japanese tissue

A second lining of Japanese tissue (11g/m² with kozo fibers) was pasted to the lined cloth strips, since it reinforced the repairs without adding any thickness. This was carried out again on a wooden board. A plastic strip was placed between the board and the strip. This would function as a barrier and prevent a section of Japanese tissue strips adhering on the board. This way, our second lining dried stretched on the board as it protruded from the plastic strip like it would on a karibari, (video 1).

Once the Japanese tissue was dry, we lifted them from the karibari with a bamboo spatula. The plastic strips delimited the area that we used to paste on the map. Finally, we cut them with a water brush so that the edges had a water-cut finish: this gave a stronger attachment to the tear repairs when pasted on the maps, (pictures 8 and 9).

Treatment

Once the materials were ready, we placed the maps on a blotter and Bondina, verso facing up. Because the maps were of a large format, we treated each half separately. Once they were dry, we reattached them together.

For both maps we squared and positioned the fragments of the maps carefully, leaving 3mm space gap for the joints, and kept them in place under weights. Wheat starch paste was applied with a noribake to the prepared strips previously placed on plastic strip. This made the handling easier and the application on the joint to be repaired. Once the strip was on the map, we applied some pressure with a shirobake over the plastic strip. The plastic strip was then removed, leaving the prepared strip on the map and we applied more pressure with a nadebake and with a Teflon spatula. It was left to dry with a Bondina, blotter and weights on top, (video 2 and picture 10).

Finally, strips of Japanese tissue (7.3g/m² with kozo fibers) were applied on the joints of the recto of the maps to reinforce the hinge on both sides of the map, (picture 11).

Results

This treatment was successful on both maps. They can now be handled and stored safely. See video 3 and after treatment pictures 12 and 13.

In preparation for the Animals: Art, Science and Sound exhibition, Conservation assessed the suitability for display of over 150 BL collection items, of which just over 120 items actually made it into the exhibition. Seventy of these items came into the conservation studio for treatment prior to being displayed. The kind of treatment for each item varied greatly. Some volumes needed intensive treatments because the covers had become completely detached, and others just needed some minor care, such as tidying board edges that had become split and frayed. Some of the paper items needed tear repairs or flattening because they had been stored rolled or folded and many of them needed window mounting so they could be framed or displayed vertically.

The conservation work for all the items was shared between many conservators in the studio. The work started in January, giving team members enough time to complete their treatments prior to the install of the exhibition in March. Conservation play an integral part of the exhibition process and without the support we provide, many of these wonderful items would not make it into the show.

Below, three conservators discuss a few items that came through the studio for treatment ahead of the exhibition.

I worked on several volumes for Animals.  My favourite was Or.917, which contains very detailed paintings of whales. . My attention was immediately caught by two in particular – as well as being beautifully painted they both have rather evocative facial expressions!

The most badly-damaged book was an early nineteenth-century volume entitled Fishes of the Ganges (Mss Eur E72). When the book came to the conservation studio the paintings themselves were in good condition, but 200 years of usage had taken their toll on the volume’s binding. The green leather of the spine was badly abraded and several pieces of it were missing. This posed a structural risk to the book, as it made it more likely that the boards would become detached at some point in the future. The red-brown paper which covered both boards was also not in a good state, with the pigment faded and rubbed away and pieces missing at the corners and edges of the boards.

Mss Eur E72 before treatment

As conservators our aim is always to retain as much original material as possible when carrying out treatment. My repairs to the marbled paper were very minimal. Using acrylic paints I toned a piece of Japanese handmade paper to a similar colour to that of the original, which I then used to fill in the gaps on the corners and edges of the boards. The damaged leather required a more interventive approach. After careful consideration I concluded that it was not possible to both keep the original leather and reinforce the binding structure. I therefore replaced the old leather with new green goatskin, but retained the old pieces so that readers can still access these remnants of the original binding. An additional result of this treatment will be that when Fishes of the Ganges returns from exhibition it will be robust enough to be consulted by readers and researchers without (hopefully) sustaining further damage.

The animal protagonist of a volume I treated for this exhibition is the horse. ‘The Anatomy of the Horse’, 1766, a printed book by the British painter George Stubbs, includes exquisite etchings engraved by Stubbs itself, which are anatomically accurate and elegant. The binding is a purple quarter leather binding with purple covering cloth on the sides of the boards and parchment reinforcement on the corners beneath the covering material. The leather spine is gold tooled with the author’s name, title and place and date of publication. The numerous plates in the text block were printed on thick laid paper.

Tab IV. Exhibition opening page.

The binding was in poor state of condition, with both boards detached, delaminated and with missing areas, and the cloth and parchment covering materials on the corners considerably abraded. The leather was split along the spine edges and was heavily worn and coming unattached on the spine, with the grain layer flaking heavily, and some missing areas at head and tail on the endcaps, along the bands and along the edges. The gold tooling on the spine was partially missing.

The conservation treatment started with the consolidation of the board corners, by reconstructing the missing areas with layers of Japanese paper adhered with a reversible adhesive. Next, we stabilised the parchment board corners with Japanese paper. The boards protected the text block again!

Once the treatment of the boards was completed, we proceeded with the removal of the old spine lining which was acidic and inflexible and caused the volume to not open well. For the lining removal, we used a poultice, locally applied to the spine to soften the lining materials and adhesives used in the past. The new spine lining, made of Japanese paper and aero-cotton, was strong and flexible and has the function to suitably support the text block spine during opening.

For the treatment of the highly degraded leather spine, together with the exhibition and loans manager and the departmental curator, we carefully evaluated the most suitable option.  Considering that the leather spine’s original state was already been lost and had no historic significance, we decided to apply a new leather spine on the book, gold tooled in the design of the original, and to keep the original pieces, consolidated, in a polyester pocket, secured into the box. With this solution, the volume could be safely displayed and handled, while as much as possible of its physical integrity was retained, with the original spine pieces available for research.

The leather reback on the spine was carried out with a goatskin leather that matched the colour and grain of the original one and was worked to the desired thickness. The treated book was finally housed in a phase box.

Historia Aethiopica is a beautiful parchment bound volume I helped treat for display in the Animals: Art, Science and Sound exhibition. This volume included three foldout folios that protruded from the text block even when folded in resulting in heavy creases and weakened paper that had led to tears and areas of loss. I surfaced cleaned the display pages and other pages I treated which displayed surface dirt, to prevent moisture from any materials used in the treatment from causing the dirt to further bond to the surface and to improve the overall appearance of the object.

I repaired all tears and areas of loss on the display page, and other fold out pages, using toned Japanese tissue so the repairs were subtle and did not draw attention, and wheat starch adhesive, a reversible water-soluble adhesive.

I used a heated spatula, with a barrier layer to protect the paper, to reduce some of the heavier creases and to flatten the corners as they were heavily curled. I also used the heated spatula in combination with some wheat starch adhesive to strengthen the edges of the page as they were extremely thin and weak, therefore were at a high risk of further deterioration.

There was also damage to the binding, a tear at the top edge between the left board and the spine, which would likely have deteriorated further during exhibition, as it would be displayed open causing more stress to this area. I repaired this by inserting a piece of unbleached shirlan cotton adhered with a mixture of EVA and wheat starch adhesive to hold the board and spine together to reduce the risk of it tearing further whilst on display or during future handling.

Both the head-edge endband and the tail-edge endband had also become almost completely detached from the text block, thus needed to be repaired. As I was unfamiliar with this type of treatment I closely observed as my mentor, Veronica Zoppi, undertook the treatment to the head-endband. This was incredibly educational as I was able to take photos and short videos of each treatment step whilst asking questions, which allowed me to make detailed notes complete with diagrams for future use and to treat the tail-edge endband.

First, I cleaned the endband and spine edge of the textblock using Konjac and Xantham gel, to improve the appearance of the endband but also so the repair materials would adhere properly.

The endband was then fixed in the right position using a strip of Japanese tissue adhered to the bottom edge of the endband and to the spine of the Textblock, this was then left to dry shut.

To reattach the endband, I sewed through the text block, around the endband core, passing again through the centre of some sections in the text block, marked by paper markers. Usually when re-attaching endbands a conservator would have access to the spine of the text-block, as the spine piece would have been partially or completely detached. As this was not the case, to allow access to the spine, the volume was held open with weights, and then a curved needle was used to reattach the endband using linen threads that closely matched the original endband colours.
