While there are many fine art applications, this book is used in the field of paper conservation when describing papers in an examination report. The reason for this is to establish a visual standard since descriptors can be quite subjective. Cream, beige and light brown to one person could be perceived as opposites to another. However, using this booklet, a large range of colors, textures and thicknesses are definitive and straightforward to select when comparing the samples to the object in person.
I first gained experience using the reference in graduate school and thought it could be a valuable resource for the Preservation Lab, especially for staff and students learning to examine objects for the first time. However, I was under the impression it was out of print because the booklet was created by the Print Council of America a few decades ago and contains a limited number of hand cut paper samples. With the lab’s newly found historic paper samples in mind, I emailed the Print Council Of America to seek permission to create a facsimile. Lo and behold, I was thrilled to learn the books were still for sale and no boot-legging necessary!
Ours arrived just this week and I’m excited to share the tri-fold booklet below! Paper colors are defined on the left, thicknesses outlined in the center, and textures displayed on the right.
How to use:
When describing a paper object (or text block) in the description section of the treatment report, I will now reference this booklet to describe the color, texture and thickness using this terminology. Colors include: Light blue, blued white (which looks gray to me!), bright white, white, cream (1), cream (2), cream (3), beige (2), and brown. There are seven types of thickness and nine types of textures to select for comparison ranging from very smooth to rough (3). The accompanying pamphlet has great information to further define the terms, including a measurement chart for the paper thickness (should you prefer using a micrometer), and provenance of all the sample papers.
Let’s use the booklet to describe a handwritten note by Abraham Lincoln from 1864, owned by the Cincinnati and Hamilton County Public Library:
During treatment, the note is removed from the matting system
Before having my hands on the booklet, I would have described the object as follows: The manuscript is handwritten with brown iron gall ink on a light beige handmade laid paper. Comparing the object to the Print Council of America sample book, the manuscript could be better described as:
…a manuscript handwritten in brown iron gall ink on a cream (1)…
…a manuscript handwritten in brown iron gall ink on a cream (1), medium (2) thick…
… a manuscript handwritten in brown iron gall ink on a cream (1), medium (2) thick, smooth, handmade laid paper.
Much improved from my initial description that indicated the color was light beige!
When using this booklet as a reference for reports or surveys, at the bottom of the report, I’ll begin adding a footnote that says, “[1] All paper descriptions by comparison with Print Council of America’s Paper Sample Book (Roy Perkinson and Elizabeth Lunning, 1996). This will allow other conservators and practitioners familiar with the book to have a point of reference when reading my report, even on the other side of the country! In the future, this can also help in identifying shifts in paper tone caused by aging paper.
Ashleigh Ferguson Schieszer – Lab Co-Manager, Rare Book and Paper Conservator
In celebration of ALA’s annual Preservation Week (April 24th-30th), Preservation Lab staff will be offering live demos and show & tells this week and next, both at UC Libraries and the Cincinnati and Hamilton County Public Library:
Each session will be unique, with different staff members showing off different aspects of preservation and conservation!
As mentioned in a previous blog post, Andrew and Naomi from Case Western Reserve came to the lab in late February to demo the MISHA portable multispectral imaging system, made possible by a National Endowment for the Humanities (NEH) Research Grant awarded to the Rochester Institute of Technology. In total, Naomi and Andrew imaged five objects from the Public Library, UC Libraries, and one of our third-party institutional clients. Imaged books included, one Otto Ege item, two Book of Hours, one undated Latin music manuscript, and a Pentateuch volume from Hebrew Union College. In all, thirteen separate capture sessions were carried out for the five objects. Afterwards, the raw data from the capture sessions was shared with the Lab via OSF (Open Science Framework) so that I could process the data in the NEH grant supported open access RCHIVE (Rochester Cultural Heritage Image processing and Visualization Environment) software.

The image gallery above shows the recto of leaf 32 from the Public Library’s copy of Fifty Original Leaves from Medieval Manuscripts, Western Europe, XII-XVI century, by Otto Ege.
While each of the capture sessions took only two minutes to complete, I found that processing the raw data took me a bit longer to figure out. Processing the data felt very similar to using CHI’s RTI Builder and Viewer software. However, in this situation I did not have a week-long training opportunity to learn the ins and outs of the software and its functions. For the Spectral Analysis App, I had only a couple of brief documents to refer to, so the learning curve was a little steeper. I also experienced some issues with the software while processing the data with the flatfield files provided from the capture session. But in the end, the processed files seemed fine without the flatfield data, so it all worked out.

The above image gallery depicts a leaf from Hebrew Union College’s Pentateuch Ms. 1 with adhesive staining, tape, and prior repairs.
What I discovered through processing all the MISHA data and then comparing it to the existing specialized imaging done in the Lab was that the suite of imaging we do in the Lab is very well rounded and, in general, suits our needs and our clientele quite well. In many cases, our results were at least comparable, if not better (specifically within the UV wavelengths) than the results accomplished using the MISHA. And, especially with our UV workflow, though our current capture time might be slightly longer than that of MISHA, the data processing time is significantly shorter and, in the case of UV especially, the side-by-side results of the accurate normal illumination next to the full color UV image(s) is ideal for our purposes.

Normal illuminationUV image (using our old setup without the UV Innovations target)
That said, I am fully aware that not everyone has access to the equipment/training that I have been fortunate to curate/experience over the last five plus years. Also, not everyone uses their finished data exactly how we do. For instance, the needs and expectations of a conservation lab and cultural heritage institutions can be very different. Even within the conservation field, how we use the data provided by specialized imaging in our hybrid book and paper lab is quite different from the kind of data needed by a fine arts conservation lab. Ultimately, I think the core audience for a system like the MISHA system is an organization looking to expand their suite of imaging services, or an institution with no multispectral imaging infrastructure interested in imaging collections in a quick and easy manner. Though for the latter, I would say that there is a big learning curve in manipulating and processing the data, but if greater focus is put into making the software and processing steps user-friendly, especially to novice users, it is completely manageable. And if this step is taken, I think the system could help a lot of institutions dive deeper into the materiality and history of their collections.

The images above depict another example of faded, scraped text. This flyleaf is from an undated Latin music manuscript that is part of the Public Library’s collection. The images below represent imaging done by the Lab, both normal illumination and UV radiation, with the goal to increase the legibility of the inscription.

In the end, multispectral imaging is just plain FUN! So, the idea of making it more accessible to a wider audience is extremely exciting and I think the work that NEH, RIT, and colleagues like Andrew and Naomi are doing to share the power and wonder of multispectral imaging is amazing. The idea of a portable multispectral imaging system with free processing software that does not take a PhD to use is boundary-breaking, and it gives us a glimpse into a future of accessible and exciting imaging, which thus allows us to see and understand more of the past. I will always be an advocate for that kind of imaging!
I love matting projects! Matting is an elegant way to present images and documentation for exhibition. We received a collection of letters and images from Abraham Lincoln in the lab from the Cincinnati and Hamilton County Public Library (CHPL) for preservation and conservation. After our conservator Ashleigh Schieszer completed the preliminary work of removing the artifacts from all the acidic and harmful elements they were previously in contact with, we collaborated on the matting choices. One cool thing I just love about this job is the opportunity to make tiny models of our intended work. Obviously, we can iron out some of the bugs and problem solve unforeseen obstacles with models, but making a tiny representation of my work is not only great to have as a future reference but is just really cool.
Matting model on left, original objects on right
So, for one of the previously matted compilations the curator suggested retaining the beautiful custom mat for the finished system. This presented a problem because of the acidity in the original mat. The solution we came up with was to create an archival buffer mat between the original mat and the artifacts. Easy-peezy.
To mount overlapping objects, we decided to secure them to different mat board layers. For example, the document on top will be attached to the back of the archival buffer with a polyester sling while the letter and portrait will be mounted to the backing board with edge strips or photo corners.
The archival buffer mat is hinged below the opened original mat.

We also added a custom portfolio for transportation and long term housing.
Yesterday we had the pleasure of a visit from Case Western Reserve University Library staff, Andrew Mancuso, Preservation Officer, and Naomi Langer, Digitization Technician.
They are currently winding up a whirl-wind month-long tour, traveling around the state to test a portable (and affordable!) multi-spectral imaging system as part of a grant from the National Endowment for the Humanities (NEH).
Andrew and Naomi unpack MISHA
Detailed setup instructions
This unique system is called MISHA, which stands for Multi-spectral Imaging System for the Humanities and Archives. The imaging system and software can be used to recover obscured and illegible text on historical documents, such as scraped-away writing:
Lost manuscript writing on a CHPL Book of Hours is a good candidate for multi-spectral imaging
If you’re familiar with multi-spectral imaging systems, you might be wondering, “How much is ‘cheap’?” Roughly, the entire system cost under $5,000 to create – with the monochrome camera and light boards making up the bulk of the price tag.
Monochrome camera fits in palm of hand
LED light boards built by RIT Chester F. Carlson Center for Imaging Science
Copy stand consists of T-slot aluminum framing and black painted wood board base
As you can see, the black Coroplast, duct tape, felt, and binder clips make up a very small portion of the budget, however, they are instrumental for using the system in a room that cannot be fully darkened. We also observed that the lights were extremely bright, and the light shield made it easier on our eyes.
Felt is clipped with binder’s clips to keep out light
To test the portable system, Ohio institutions with medieval parchment documents from Otto Ege collections were asked if their manuscript leaves could be imaged on-site with this equipment. With the entire glamour shot studio fitting into a 40-pound rolling suitcase, Andrew and Naomi traveled to various cities from Cleveland to Cincinnati, making our photographic imaging dreams come true!
This tightly fitting suitcase has packing instructions to protect all the parts.
Since the Cincinnati and Hamilton County Public Library (CHPL) own multiple Ege collections and a variety of other worthy imaging candidates, the Preservation Lab was fortunate enough to participate. In the CHPL collection, manuscript 32 (of Fifty original leaves from medieval manuscripts, Western Europe, XII-XVI century) was thought to be the most promising to reveal hidden information.

Now that the photographic capture is complete, we’re looking forward to processing the images next with the open access software called Hoku, provided by the Rochester Cultural Heritage Imaging, Visualization, and Education (R-Chive) community.
We were thrilled to see how easy this equipment was to set up in person. And special thanks to Andrew who brought his handy adaptable book conservation support (ABCS) to cradle our bound collections. Everyone should have one!
In 2017, an Indian religious text known as a Kalpa-sūtra entered the lab in desperate need for improved storage. Being unfamiliar with this type of religious manuscript I jotted down notes in preparation for housing the item and came up with a basic housing solution. I briefly familiarized myself with terminology, format, and condition needs. This is a summary of those findings with links to resources.
Cincinnati and Hamilton County Public Library sent their Kalpa-sūtra to the Preservation Lab to receive improved storage. The original storage enclosure was not archival and did not properly fit the manuscript. This left the manuscript vulnerable to damage.
Kalpa-sūtra
Kalpa-sūtra translates to “the Book of Ritual” that was meant to be read daily. It follows a 3-part textural structure. The first part consists of the ‘Lives of the Jinas (an enlightened human being)’ and describes the lives of well-known figures. The second section, known as the ‘String of Elders’ celebrates early teachers of Jainism. And the final section, referred to as the ‘Right Monastic Conduct,’ provides rules to follow during the rainy time of year. The ‘rainy season,’ as it is often referred to, is a time of year when the festival of Paryusan is celebrated and the Kalpa-sutra is heavily used.
Jainism
Jainism is an Indian religion that shares similarities to Buddhism and Hinduism, but is regarded as a separate religion. It’s believed to have originated in the 7th – 5th century BCE in the Ganges basin of Eastern India. Jains believe in karma, reincarnation and practicing non-violence to all living creatures. While learning more, I appreciated this article that described the Jain’s thoughtful practice of non-violence by explaining how Jains eat above-ground veggies but avoid eating roots of vegetables so as not to kill the plant.
Format
Earlier Kalpa-sūtra were written on palm leaves and stored in between decorated wooden covers. They were bound with rope or cord through holes punched in the center of the leaves and are read by flipping the leaves up, from bottom to top. To see an example of a palm leaf book, check out this one housed by the Preservation Lab in 2016.
Later Kalpa-sūtra, such as this one owned and digitized by the Public Library, were written on paper beginning in the 14th century but still follow the same horizontal single-sheet format of the palm leaf. Often they were hand colored, illuminated in gold, and written in a black ink calligraphic style on laid handmade paper. Like many others, the Public Library’s manuscript contains 135 individual loose leaves that have never been bound. The leaves, also referred to as folios, were traditionally written on both sides with seven lines of text.
To learn more about formats of Jain manuscripts please refer to Jainpedia.org.
Decorative Themes
The Public Library’s manuscript is a good example of a traditional paper Kalpa-sūtra manuscript. Its decoration consists of left and right margin lines, and decorative diamond-shaped marks that interrupt the text. The diamonds (often found as circles in other manuscripts) descend directly from the tradition of punching holes in palm leaf books for binding. They are located in similar locations to palm leaf holes and are predetermined when the text is written. On the recto of leaves there are three gold decorative diamonds, one located in the center and one each along the right and left margins. (The V&A refers to these decorations as “central and marginal string holes that are not pierced.”) The verso of leaves contain only one decorative diamond in the center. The religious manuscript is paginated on the recto in both calligraphy and graphite.
The three diamond shaped decorations descend from the tradition of punching holes in palm leaf books for binding. Palm leaf books were bound with strands of cord.
Public Library illuminations consist of red and blue opaque watercolor and gold illumination. The very base of the paintings are a thin open weave cloth attached directly to the handmade paper. On some leaves, you can see where this thin cloth is folded over onto the other side of the leaf.
Purple arrows point to a cloth that is wrapped around from the front of the manuscript folio.
In my research, I tried to understand how paper Kalpa-sūtra were traditionally stored. It is noted on Jainpedia.org that Jain manuscripts appear to have been stored within decorated covers of paper, cloth, and wood.
From what I can gather by surveying a collection of digitized manuscripts, loose sheets appear to have been stored within chemise-like covers, sometimes with multiple flaps, such as this one from the British Library (Or. 13950) andGamma 453 where a loose manuscript is stored within a cloth cover:
I also discovered some Kalpa-sūtra that had been treated in western traditions. Below are a few examples that include where one is tipped along the bottom edge and bound into a western style half leather binding. Another, MS 22393, appears to be bound along the top edge at the British Library. A third yet, MS 34, at the Royal Asiatic Society is bound in half leather with marbled paper:
Others found online have been inlaid into larger sheets of paper, such as the one below from the Victoria and Albert Museum. Manuscripts heavily illuminated and likely suffering from pigment corrosion have been encapsulated between sheets of plastic or glass, such as these from the British Library (Or. 14262 and Or. 13950). One manuscript has been both inlaid into paper and encapsulated:
There does not appear to be a conservation standard for storing Kalpa-sūtra manuscripts.
Storage solutions vary widely and are specific to how they will be displayed or handled.
While I appreciate the western tradition of binding loose pages to prevent them from becoming lost, I knew the Public Library preferred to house the manuscript with as little reformatting as possible in order to preserve cultural traditions.
While I came across a few examples that appear to be stored unbound within covers, it was unclear as to the date of the covers, when they were added, and how they might have been formatted. No images were provided of the sides of the covers.
Even though heavier than plastic, glass was likely used for encapsulation to protect the flaking and corroding illuminations from the static charge of plastic.
Conclusion
The housing solution selected at the lab is one of many options and provides a stop-gap until a more traditional format can be explored.
The most severely corroded leaves at the front and back of the text were encapsulated between glass while the rest of the leaves were left loose. This allowed the most vulnerable leaves to be protected from humidity while avoiding the weight of encapsulating the entirety of the manuscript.
The encapsulated and loose manuscript leaves were then stored together (the outer encapsulated leaves helped serve as de facto covers). An Asian four-flap enclosure with bone clasps was custom made to provide structure and stability, as well as perhaps provide a format more sympathetic in style to a Jain holder than a European style enclosure.
Damaged outer leaves are encapsulated while inner leaves are stored in a two-flap paper chemise
Further Research
There is much ripe for future study:
I hope to experience a historic Jain manuscript cover in person to learn the format and structure.
There are downsides to using glass that should be reconsidered in the future: 1. Glass is heavy and breakable. If the glass breaks, it could cause tears in the fragile paper. 2. Glass deteriorates in humid conditions. The alkali will eventually leach out and could cause staining in the paper. This storage solution should be considered a temporary solution until the pigments can be studied and safely consolidated.
Since there is a pigment contributing to corrosion and paper drop-out in the manuscript, it is likely that pigments in the Public Library manuscript contain copper. I would be interested in developing a plan to analyze the pigments to better understand their composition.
As a library book and paper conservator, I am less familiar with fine art painting traditions on paper, particularly Indian painting. This was my first experience with observing an open weave cloth used as a base for illuminated manuscripts. This initial research has me captivated to learn more about the traditions of Indian miniature painting and how they are connected with early stylized Kalpa-sūtra paintings, and if their implications for inherent condition issues can be extrapolated.
The word ‘sutra’ is literally interpreted as “thread” in Sanskrit. Different manuscripts contain the word “sutra” in their title, such as the Indian Kama Sutra, or Asian Buddhist sutras which are not to be confused with the Kalpa-sūtra. Is it possible that because these manuscripts were historically bound with cords or wrapped with ties give rise to the word sutra?
Interesting Side Note
I learned that The Diamond Sutra owned by the British Library is considered the oldest block printed book in existence AND it has been analyzed to find the scroll’s yellow plant dye extract, Berberine, is toxic. It’s possible the toxin can be absorbed through the skin (so those handling should wear gloves!) as mentioned in the Vol. 21, Number 4, Nov. 1997 Abbey Newsletter under the heading Peril in Old Paper.

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.
