At the end of October we were lucky enough to have Jeff Peachey come to the Lab for a week-long workshop on Leather Conservation. We covered sewing extensions, joint tacketing, board splitting and cotton hinges, leather rebacks, and knife sharpening. In the weeks following the workshop we shared highlights from the workshop on our Instagram…
Leather rebacks, including board slitting, inserting a cloth hinge, lifting the original leather, dyeing the new leather, and paring and attaching the reback.
Finally, conservation ASMR…Jeff Peachey style! Make sure the sound is on for this one…
We had the best time with Jeff. He is such a knowledgable and approachable instructor, and we learned so much from him. Thanks for coming to the Preservation Lab, Jeff!
John Robinson’s circus was a famous, traveling, family-owned circus’ that toured the United States for 69 years beginning in 1842. The family business stopped touring around 1910 and was officially sold in 1916. It was managed by four generations, all named John Robinson.
As a local tidbit to note, the circus was stationed during the winters near Cincinnati, OH, where the family owners kept Tillie, the beloved elephant. Tillie was said to roam the neighborhood of Terrace Park and was well known in the community and beyond. Many stories were written of heroic accounts and even her ability to “talk”. She was memorialized when she passed in 1932 and a marker can be found at Circus Place in Terrace Park today.

Cincinnati and Hamilton County Photographic Album
A rare photographic album owned by the Cincinnati and Hamilton County Public Library (CHPL) dates to the late 19th to early 20th century and contains albumen portraits of John Robinson’s circus performers. The images have been fully digitized after receiving treatment to improve legibility at the Preservation Lab. The CHPL Digital Library catalog describes the object as follows:
“Album of 266 photographs of varying sizes. Most are portraits of Robinson family members and of the circus staff and performers. Included are group portraits of the work crew, musicians, clowns, acrobats, novelty acts, and family acts, and circus animals. Many of the individual portraits are of side-show performers such as tattooed men, albinos, women with floor-length hair, dwarfs, etc. Some of these are studio shots that may have been sold or used as advertising. A small number have captions, and the few with dates are from 1901-1909.”

Toned Images
While the content of the images is spellbinding, the album is also unique as many of the photographs appear to be once toned overall with pink, yellow, or orange colors.
An online reference from the American Institute for Conservation (AIC) Preprints in 1980 refers to historic albumen photographs that were dyed and are extremely light sensitive. In the article, James Reilly states, “A great deal of the paper sold during the 1880’s and 1890’s was “doubly albumenized”, i.e., floated twice to obtain maximum gloss. Another common practice was the addition of aniline dyes to the albumen solution. Tinted paper was mainly used for portraits, and the most popular tint appeared to be pink, but various shades of purple, blue and even green were also used. Because the dyes had such poor lightfastness–especially in such dilute solution–most of the dyed paper is difficult to recognize today.” It’s fun to imagine that these tinted papers might have been used to capture and celebrate the lives of circus performers in John Robinson’s 10 big shows.
Many of the colors in the photograph album have faded irregularly, with the pink being the most prominent color remaining. This colored photograph phenomenon does not appear to be widely documented elsewhere as the fugitive dyes were not light-fast. They may have also been susceptible to dark fading and chemical instability. Because these photos were preserved within pages in an album, it’s possible they’ve been protected from light and some of the more chemically stable images have not yet completely faded, allowing us a glimpse of this rare format.
While treatment cannot be performed to recolor the images, some photographs did receive conservation treatment to improve visual legibility. There were nearly 30 images that appeared to have a dark discoloration. These photographs were identified to be missing fragments of paper backings. As a result, the dark album pages behind the photographs were obscuring the visibility of the photographic emulsion layer. Some of the more badly damaged images were carefully lifted, relined and reattached. Others received general surface cleaning. A few examples of improved readability are below.
Ashleigh Ferguson Schieszer (CHPL) – Special Collections Conservator
In February 2019, the Lab received a unique item at the special collections’ meetings for the UC Libraries, a Book of Hours (ms.37) from 1475 from the Archives and Rare Books Library. I was so excited when this book came into the Lab.
This 15th century Book of Hours was in poor condition and in need of conservation treatment. Not only was the binding structure failing and the text block broken in half, but this book was also heavily used as a teaching tool at the ARB library, and in its current condition it could not be safely handled. This was the perfect project for Ashleigh and I to collaborate.
From the beginning, it was decided that in conjunction with the conservation treatment of the Book of Hours, I would create a book model like the original Book of Hours, to be used as a teaching tool in the ARB library collection. In addition, the model would have a leather chemise, a common feature in some Book of Hours of the time.
The Book of Hours MODEL with a removable chemise.
Now here is where this story begins with the model of the Book of Hours. Often, here in the lab, we all create book models for various reasons: to learn about a new treatment, test different treatment options, to understand how some materials work together, and as teaching tools.
As a teaching tool in the ARB library collection, this model needed to resemble the original Book of Hours in its structure and materials used.
The primary goal for this model was to show how a Book of Hours was historically built, its sewing structure, the materials used, and also to provide the ARB library with a book that could be easily handled by students and scholars.
Once the treatment for the Book of Hours was fully established and confirmed with the ARB curator, I was able to start working on the book model. I will save you form reading about all the different steps of making the model, but here are the main features of model:
Endsheets with leather hinge – Two bifolios of calligraphy goat parchment skin wrapped along the spine edge with a hinge of Allum tawed leather (later would be used as pastedowns)
Sewing – Sewn on three double raised cords with a linen 18/3 thread. The dimensions of the text block and sewing holes, were guided from the original sewing holes of the Book of Hours.
Endbands – Primary conservation endband with the bead on the spine, and secondary endband with the bead on the text block.
Spine linings:
Reversible layer of Usu Gami thin and Zen Shofu wheat starch paste.
Slotted Airplane cotton cloth with flanges to be used as board attachments.
Cover
Boards – Oak wood
Board attachment – Boards were laced with the sewing supports through carved channels
Covering material – Full alum tawed leather binding with removable chemise
Clasps – Brass tension clasps (these were created in-house by Chris Voynovich, and he did an amazing job).
Upper cover.Lower cover with the tension clasps (created by Chris)
There was no evidence that the original Book of Hours had clasps, but the curator requested tension clasps for the book model. Clasps were common in the 15th century bookbinding, and this would provide the students with the experience of handling a book with clasps and allow them to understand their function.

Chris created these using brass plates.As a teaching model, the interior of the upper cover was left exposed to show how the boards were laced and what material was used.On the lower cover, the pastedown was adhered. An alum tawed pastedown was not very common for the time of the Book of Hours.
The curator also requested that one of the pastedowns be kept unattached, so the students could see how the boards were attached to the text block and that they were wooden boards.
In addition, I created a removable chemise, also requested by the curator of the ARB library. In some Books of Hours, it was common to have a leather chemise, but most often they were not removable. The chemise was created from a vegetable tanned goat split skin.

Stay tuned for a future blog post where we will dive into the conservation treatment and research we did on the Book of Hours (ms.37).
The Preservation Lab has enjoyed our involvement in the Vesalius lecture series and exhibits including preparing the loan agreements, leading and assisting with photographic documentation, and providing spectral and computational imaging to the Vesalius researchers and lecturers.
Some of this work made a guest appearance on the FoxNews 19 segment, starring Dr. Stephen Joffe, on the three rare books that had been on view in December in the Winkler Center.
Winter is approaching here in Cincinnati, far too quickly for my taste! But at the Lab we have been thinking about a winter staple a bit differently… The sled! A book sled, that is. This open-topped carrier of bound treasures has become the newest edition to our enclosure family. It is perfect for housing oversized books to be stored flat, as it enables easy transport of these large tomes, without adding too much extra weight.
The sled has been honed and developed over the years by conservation professionals, but it has its roots at the Newberry in Chicago, where they were used to house their large antiphonary collection. I had the privilege of working at the Newberry prior to joining the incredible team here at The Preservation Lab, so the idea of starting to create book sleds at the Lab has been lurking at the back of my mind. At the Newberry, I was able to create my very first book sled, and understand the simple, yet highly functional structure.

The book sled was refined by Ann Lindsey and Melina Avery from the University of Chicago when they treated and housed a 52-pound antiphonary from their collection. They were able to design a sled with additional walls and stronger reinforcements. Chris Saclolo from the University of Central Florida further enhanced the book sled by adding wall reinforcements and a removable lower tray.
When the Lab received an elephant folio from the University of Cincinnati Classic’s Library that needed treatment and housing, we were able to create the very first book sled at our Lab! Housing a book over 20 inches tall is no easy feat, so we were thrilled to be able to use the experience and advice from our fellow conservation professionals. I worked alongside Chris Voynovich and Catarina Figueirinhas (because 3 minds are so much better than 1) where we problem solved, planned, and constructed this large book sled. The finished sled design closely follows Saclolo’s recommendations, with minor adjustments to the tray, as our book did not have bosses.

Catarina was able to create a model that we can use as a reference in the future.
Ultimately, the book sled will allow the book, Facsimiles of National Manuscripts of Ireland, to be visible on the shelf while also aiding in transporting the book through the library when needed. It will also prevent additional damage and abrasion to the leather at the spine, which received a reback during treatment.

We already have additional oversized books in the Lab for treatment, so more sleds will be on the docket this winter!
Join the Preservation Lab staff on Wednesday, October 20th at 3pm (EST) for an quick Instagram Live event centered around a collection of Japanese bindings that were recently conserved and are now in the process of receiving specialized, custom enclosures. We’ll be talking about the two different types of bindings in the collection, creating Japanese four-sided enclosures, why we make models, and answering any questions you might have!
Mark your calendars, or better yet, follow us on Instagram @thepreservationlab for updates, because you won’t want to miss this behind-the-scenes look at what goes on in the Lab. See you then!
One of the exciting things about the Preservation Lab is you never know what’s going to come into the Lab next! Sure, sometimes we know a little bit ahead of time about upcoming projects, but usually the special collections intake meetings are filled with “oohh’s”, “aahh’s” and sometimes “oh no’s”. But it’s not very often that you get to work on a project, here in Cincinnati, while the objects themselves are across the Atlantic. Combine that with RTI (Reflectance Transformation Imaging), a variety of Vesalius related texts, and an opportunity to collaborate with other photographers, and you’ve got a recipe for one exciting project!
Currently in the planning stages, the Winkler Center for the History of the Health Professions will host a series of Cecil Striker lectures and a physical exhibition that will celebrate the work of Andreas Vesalius. The series and exhibition is entitled The Illustrated Human: the Impact of Andreas Vesalius and is sponsored by Stephen and Sandra Joffe. Vesalius was a renowned 16th century author and physician, whose iconic work on human anatomy, De Humani Corporis Fabrica Libri Septem, is considered one of the most influential anatomy books ever written. Three rare first edition Vesalius volumes will be exhibited during this upcoming lecture series, gratuitously on loan from Stephen and Sandra Joffe. Dr. Joffe is a long-time UC supporter and an emeritus faculty member.
For the upcoming exhibit, the Lab will be creating custom supports, as needed, to display the volumes, and providing imaging of various pages and illustrations for promotion. I will also be doing any additional specialized imaging that might be helpful.
Since we believe that some, if not all three bindings coming to Cincinnati, might be original to the volumes, and we immediately thought of RTI and wondered if it could provide new insights to researchers. After seeing the wonders of RTI, via RTI examples from the Lab, the owners of the Vesalius editions were interested in having RTI done on a selection of Vesalius items in their collection, including some that wouldn’t be coming to the Lab. The only hitch? The volumes are at their home in Scotland. The solution: hire a local photographer, Iain McLean, to carry out the capture portion of the RTI in Scotland, and have the files shared with the Lab for processing and rendering. Though Iain is an established commercial photographer with a digital imaging background, RTI was a new adventure for him, so I shared some resources with him, including CHI’s Guide to Highlight Image Capture and some notes and resources created by the Lab during our various capture sessions. Iain and I then met via Zoom in mid- August to discuss the ins and outs of RTI highlight capture prior to his capture session on August 20th. Iain also brought his colleague and fellow photographer, John Linton, into the fold to assist him during the capture session, which I recommended highly because though it might be possible to do RTI solo, I can’t imagine a capture session without my normal collaborator and the Lab’s Assistant Conservator, Catarina Figueirinhas. The session would take double the time and I’d make five times the mistakes without Cat! (Check out a time lapse video of Cat and I doing RTI in the Lab on our YouTube channel).

After a successful test capture session, Iain and John were ready for the main capture session on August 20th. They ended up capturing the front and back covers of seven volumes. Once the massive capture session was completed, Iain shared the jpegs with me so that I could begin processing the images in RTI Builder and then rendering the snapshots in RTI Viewer.
This is a time lapse video of the capture session. (This video was created by Iain and kindly shared with me.)
After processing the 679 images and rendering the snapshots, here are some of my favorite finds:
This a side-by-side of an upper cover. The left image shows the default lighting mode in RTI Viewer and the right show the specular enhancement mode. On the right, just above the center panel, you can see the letters GFV (above the panel) and 1567 (below the panel), which are much more visible with the specular enhancement mode than under normal illumination.Here you can see a detailed composite of another cover’s center panel. On the left is the default/normal illumination mode, the center shows the normals visualization mode, and the right is the specular enhancement mode. You can see by employing the two specialized RTI modes the ornate detail of the cover is far more readable.
This composite of the upper cover features the diffuse gain mode on the upper left half, and the default lighting mode on the lower left half. The diffuse gain mode really accentuates the features of the man in the center panel.
This is a composite of the lower cover of the same volume (my favorite binding of the group). This shows the default on the upper left and specular enhancement on the lower right.
This composite of another upper cover shows the default mode on the left and the specular enhancement mode on the right. With this one, the discoloration of the cover distracts the eye and pulls it away from the detail of the decoration, but with the specular enhancement mode you can eliminate the color completely and modify the secularity so that your eye can focus solely on the elaborate detail.
This was such a fun experience for me, and I really enjoyed collaborating with colleagues outside the conservation field and across the pond! And I look forward to the condition photography of the three volumes and any additional specialized photography that might be helpful.
Special thank you to Stephen and Sandra Joffe for allowing their important collection items to be photographed, and for giving the Lab full permission to use the generated images. Also, a very special thanks to photographers Iain McLean and John Linton for capturing these covers and for collaborating with me on this exciting project.
To celebrate nationalPreservation Week (April 25 – May1, 2021), staff at the Preservation Lab are sharing the following answers to the question below as they reflect upon the wealth of library resources located in the Cincinnati community:
What is your favorite treatment or project that you have worked on in the Lab?
Jessica Ebert:
Learning a new photographic imaging technique, RTI
In April of 2017 I had the amazing opportunity of attending a 4-day workshop at Yale University to learn Reflectance Transformation Imaging (RTI) from the experts at Cultural Heritage Imaging. It was one of the most exciting experiences of my career, and when I came back to the Lab to show the staff what I had learned, Aller Bucher Und Schrifften volume from Martin Luther was one of the first items we captured with RTI. I remember that moment when Catarina and I completed the capture and processed the images – we were just in awe of everything we could see with RTI that we couldn’t under normal illumination. Since then, we’ve made changes to our equipment and our workflow, so now the results are even better than they were back then…but this will always be my favorite.
The left side of the image shows the front cover under normal illumination, or what you see with your naked eye, whereas the right side is a RTI generated image using the specular enhancement mode.
This generated snapshot illustrates the Static Multi Light mode. Below the center panel that features a portrait of Martin Luther you can see “1571”, and above the panel you can see “ID”, both of which are virtually impossible to see in the normal illumination image.
Of all the projects I have worked on at the Preservation Lab, this item is by far one of my ultimate favorite treatments I was able to perform. This book was brought to the Preservation Lab in poor condition. The book had no binding, the text block was split in multiple areas, the sewing was broken, and several pages of the text block where either torn or had extensive loss. In addition, most of the text block showed signs of water damage. Since this book was in such poor condition and the curator of the collection wanted the book to be handled by scholars and the public, it was necessary to do a full conservation treatment.
I was thrilled when I got assigned to this book treatment. I love to work on any book, but the more complicated or involved treatments the better and this was definitely the case. In this treatment, I was able to repair the text block, reduce some of the tideline staining, fill losses and resew the entire text block, while also creating a new binding (called a split board binding) that is strong and flexible to allow such a heavy book to be read.
Before Treatment – Initial condition of the book when it was received by the Preservation Lab. The text block was split, the sewing was broken, and several pages were torn or had paper loss.
After Treatment – Conservation treatment complete. After the text block was repaired and resewn, the book received a new split board binding that allowed the heavy book to be read while mitigating further damage.
After Treatment – The new split board binding provided the book a more flexible opening.
This treatment took a long time to complete, and to this day it is still one of the projects that I have enjoyed the most. Click here to see the complete treatment report and all the photographic documentation.

Iron gall ink treatment of the CHPL Jones Account Book
Washing and rebinding treatments are always a favorite when they come across my bench, as they allow a highly damaged item to become usable and accessible once again. An account book of Jones and Rammelsberg offered one such treatment as it came to the lab with a myriad of issues: a damaged book block without a binding, corroding iron gall ink, previous mold damage, and a shocking amount of pest evidence. The treatment is incredibly memorable because to tackle the issues of aging iron gall ink I was able wash the pages of the book block using a calcium phytate bath to stabilize the manuscript. Once the washing was complete, I was able to resew and rebind the book block, making it whole, functional, and protected once again. It is rare and special to have done such an involved treatment, but in this case the in-depth steps allowed previous damage to be treated and helped remedy the inherent vice of aging materials.
The book block before treatment was highly damaged, so much so, that it was difficult for library patrons and staff to access and use the item without a cover.
Handling the book, you’d never know the hours of labor that went into the treatment (including learning!), but its functional form makes it ready for use once again.
Creating the Italian ledger binding for our teaching model collection
The lab creates a lot of models. Many of these models are made in preparation for treatments. However, some models are created with instruction or engagement in mind. These models, such as the Italian stationery binding (laminated archival bind) I created, help illustrate the history of the book as its form and manufacturing process change over time. Check out the model at the blog entry where you can see a video of the binding being handled. Follow the instructions on the blog make you very own, and in the future, come see it for yourself when our in-person open houses resume in the future.

Treatment of a Haggadahowned by Hebrew Union College
I particularly enjoy the problem solving nature of special collection treatments and thus, my “favorite” treatment is usually the one I’m working on. Currently, I’m treating a Haggadah owned by Hebrew Union College that dates to 1526 or 1527. While I’ve treated other haggadahs from HUC, including this one, this project involved iron gall ink treatment AND rebinding a textblock with two different sized leaves, or pages, into its original historic leather cover. Because the binding had been previously treated and reformatted with materials that did not age well, collaboration with the librarians at HUC required exploration into whether we wanted to re-create the past reformatting option with longer lasting materials, or perhaps, explore a new option altogether. Before we committed to a solution, I created a model to test out a new option since unanticipated questions or outcomes often arise during experimental pursuits. For that reason, it’s better to problem solve on a model, rather than on an actual special collection material. In the end, the librarians and I were happy with the results of the new option, and I’m currently at the stage where I’m ready to start rebinding the pages of the actual object.
The top image shows the book open to smaller sized printed leaves before treatment. Leaves are previously reformatted with yellowed tape along the edges, attached to larger paper frames. Paper frames are cockled and distorted. The middle image shows a detail of untrimmed, full-size manuscript leaves. The bottom image shows the fore edge of the binding before treatment.
These images show the model that explores a solution to encapsulate the smaller pages into polyester sleeves that could be sewn into the binding next to the larger pages. This required staff to weld polyester sleeves with paper hinges that could be sewn through like a gathering.
The image shows the binding ready for resewing with its new encapsulated leaves, or pages, next to the created model.
Not only was this piece based on a favorite subject of mine (I love Shakespeare!), this was a historic photograph treatment I was able to handle with just a little guidance. I was able to properly identify the photographic elements on the first try, performed a surface cleaning on the piece, and created my very first cloth-covered clamshell and cradle to house it. It was such a wealth of learning experiences within one project, which is the best part of my work!

Constructing a custom cloth-covered enclosure to house the Public Library’s William S. Porter Collection of photographs
One of my favorite aspects of the job here, in the lab, is designing and creating custom enclosures. This collection of rare daguerreotypes, ambrotypes, and tintypes is an example of adapting a standard cloth covered clamshell to accommodate a collection. I created two trays with pull tabs that are removable for easy access and display. Each photograph has its own tuxedo box and is set in polyethylene foam (Volara) for protection. The tuxedo box enclosures are identical in size to reduce confusion while repacking. Check out this blog created by Jessica that shows a gif of the enclosure opening and closing, and this blog post showing a similar enclosure I created for a dairy collection.

We recently shared a blog post on the Cincinnati & Hamilton County Public Library’s blog that serves as a companion post to this one. Both posts focus on the repair of two CHPL books, Covered Bridges and When Art Meets Design, that received split-board binding treatments carried out by Kasie. While this post focuses on the treatment itself, the other illustrates the journey of a circulating book through treatment in the lab (and at home) and its eventual return to the library. We highly recommend checking out A Journey from Broken to Mended: Repairing Books in the Preservation Lab.
As a hybrid conservation lab, we treat and house both special collection items and general circulating collection items, as well as everything in between. Special collection items are rare or archival materials that typically do not circulate; basically, books and other objects that you can’t take home with you, are out of print, valuable, and/or are less readily available locally, nationally or even globally. General circulating collections are typically books that can be checked out and taken home, and tend to be newer books, books still in print, and/or more popular books. Since we are a collaborative lab that means that we treat and house special collections and general collections from both the University of Cincinnati Libraries (UCL) and the Cincinnati & Hamilton County Public Library (CHPL).
Due to the nature of these two types of collections (general and special), the treatment, documentation and who treats what is very different. Before the pandemic, most of the staff’s time was dedicated to special collection items or the items that fall between the two categories, which we call medium rare, and our students and volunteers, with plenty of hands-on, one-on-one training, handled the bulk of our general collection repairs. But then working from home, all or a majority of the time, became the norm for Lab staff and we had to shift focus and turn to taking on more general collection repairs that we could more easily take home with us. Initially, we took home more difficult sewing projects and mending projects that our students or volunteers either hadn’t gotten to yet or were avoiding for one reason or another. Then, after we could return to the Lab in some capacity to prep our own materials, we realized that split-board bindings* were the ideal general collections treatment for staff to work on from home.
A split-board binding is a new binding or case that incorporates several newly added reinforcement elements that are then sandwiched between two pieces of board that make up the front and back covers.
Kasie’s split board binding cutaway model
Each technician has a cutaway model that they’ve made, so they can easily reference it during treatment.
With the cutaway model you can see the various aspects of the treatment.
Split-board bindings are a great solution for oversized, heavy books like coffee table books and art books with glossy pages, which are very common in both UCL and CHPL general circulating collections. They are also, by far, the most complex general collections treatment we perform in the lab and have always been done by the conservation technicians, instead of our students or volunteers. This is not only because of the complexity of the treatment, but also because of the lengthy treatment time involved; a student or volunteer’s limited weekly schedule in the lab is not conducive to such an extensive treatment. Though it was a general collections treatment reserved solely for the conservation technicians, prior to March 2020 the techs unfortunately had little time to work on these treatments, as our focus was primarily on special collections treatments and housing. Therefore, we had amassed a little backlog of split-board binding treatments – enter quarantine and working from home!
One question that might come to mind, if split-board bindings are so elaborate and extensive, why do them on general collections items at all? Why not just buy a new copy; wouldn’t that be more cost effective? Typically, the books that warrant a split-board binding are more pricey, glossy paged, oversized books, like art and architecture books. And unfortunately, though these books have a much higher retail price than your average James Patterson novel, the construction is generally less than ideal. These books might have beautifully printed, full-color, thick and glossy pages and dynamic cover art, which makes them attractive to the reader, but they also are often sewn with very thin, fragile thread that easily breaks. The spines are generally lined with a layer of rigid plasticized glue that can become very brittle over time. Often, the covers or cases are constructed solely of printed paper, not cloth, and generally have a thick piece of board along the spine (which we call a flat back) that doesn’t allow the book to flex properly when opened and can actually make the spine break down and tear in record time. It is not uncommon for these books to have little to no reinforcement in the attachment of the textblock to the binding (i.e. how the block of pages is attached to the cover), which makes the heavy textblock break away from the cover quite easily with use.

But why are these books constructed so poorly? These large coffee table and art books are constructed with individual use in mind, not with the frequent use and circulation that comes with a library collection item. The split-board treatment, along with many general collection repairs, improves on a bad binding design and makes the book stronger and sturdier, using better binding techniques and materials that can better stand up to use by many library patrons.
A split-board binding treatment involves creating a new binding with new sewn-on endsheets that are reinforced with cloth, at least three sewn on linen tapes (supports), new spine linings, and a new quarter bound case created with two boards at the front cover and two at the back cover, and generally an inlaying of the original cover designs. However, additional elements of treatment may be warranted based on the condition of the book, such as broken sewing, tears, detached leaves, etc. The steps generally proceed in the following order:
Prepare materials in the Lab – new endsheets, starched reinforcing cloth, linen tapes, spine linings, binders board, bookcloth and Bristol board for inlays.
Detach textblock from cover, if needed.
Remove original spine linings, mechanically and with poultices.
If broken, remove original sewing thread and disbind textblock.
Mend any tears and guard any separated, torn or detached leaves.
Sew to include linen tape supports and new endsheets using French link stitch – whether partial/added sewing over the original sewing or complete resewing is dependent on whether the original sewing was intact or if it was broken and the textblock disbound.
Round and back spine, as needed.
New spine linings adhered to the spine:
Reversible layer of kozo fiber tissue with wheat starch paste.
Original stuck-on endbands, if present, or new endbands.
Cloth reinforcement lining (Cambric) with flanges that extends past the spine on both sides.
Several paper linings to further support the textblock.
Create “laminated flanges”, the key characteristic of a split-board binding, using the sewn on linen tapes, the flanged cloth piece adhered to the spine, and the first and last leaves of the new endsheets. Cut laminated flanges into thirds, with the center portion incorporating all the linen tapes.
If the original covers included artwork that should be retained, mechanically remove from the original boards. Remove remaining board backing with poultice.
Remove and clean the original spine.
Cut binder’s board to size – 2 pieces of board are cut for both the front and back covers (4 pieces total). The thickness of the boards used is dependent on the shoulder of the book.
Determine placement of the board and adhere the middle laminated flange segment to the top of inner board, keeping the top and bottom laminated flange segment under the inner board, unattached. Adhere the outer board to the inner, thus sandwiching the middle laminated flange section between the two boards.
If the original cover is being inlayed, create and attach an inlay border of thin Bristol board to the cover boards, as needed.
Covering the boards:
Attach the spine cloth piece and turn in at the head and tail.
Attach the board cloth to the upper and lower boards and turn in the edges.
Bevel the remaining laminated flanges and sewn on cloth reinforcement (Cambric) slightly and attach both, in sequence, to the inner boards.
Adhere the pastedowns and trim the remaining sewn on Cambric to roughly 1/8” – ¼”.
If there are cover inlays, adhere the inlay(s) to the cover(s) within the inlay border.
Adhere the original spine to the new spine of the case.

Completed treatment
When completed the treatment offers a substantial amount of support to the textblock and a robust attachment of the textblock to the new case. While it is an involved treatment that requires a good amount of preparation, work and skill, the end results are worth it all, and the improvements are significant.
Treatments of this magnitude take many, many hours over the course of several weeks. Often, only a few steps of the treatment can be accomplished at a time to account for drying time, and timing out visits to the Lab. To take a sneak peak at what some of the steps of treatment look like please check out the video below:
For an example of how Kasie used a split-board binding treatment and modified it for a special collection item that came to the Lab from UC’s Winkler Center without a case, check out her blog, A Monster of a Treatment.
We hope you’ve enjoyed this peek into a split-board binding treatment! If you did and you want to see more of what we do, and see the Lab, then please check out our Virtual Lab Tour which will take place on Tuesday, January 26th at noon, live on the Cincinnati & Hamilton County Public Library’s Facebook page. For forthcoming information about the Virtual Tour follow the Public Library on Facebook and follow the Lab on Instagram (@thepreservationlab).
*This treatment was originally designed at the Brigham Young University lab. Then it was brought to the University of Kansas lab by Brian Baird, where our conservator, Ashleigh Ferguson Schieszer, learned the treatment and thus brought it to the Preservation Lab.
