Kenneth Spencer Research Library

The conservation lab at the University of Kansas Libraries is now home to a pair of Adjustable Conservation Book Supports, or ACBS’s. The ACBS is a hinged cradle that supports a book during conservation treatment; fiberglass rods gently hold the book open in almost any desired position, a feat that can be difficult or impossible to achieve with our usual system using weights and fixed cradles or foam wedges, or other rigged-up arrangements. The ACBS was designed and developed at Northwestern University by conservator Roger Williams in collaboration with students in Northwestern’s School of Engineering. Williams wrote about the process in this blog post: Collaborating with engineering students to create an open-design conservation tool – LIBRARIES | Blog (northwestern.edu). We learned about the ACBS when Williams presented a webinar about the project during the COVID-19 pandemic, at a time when many conservators were unable to work in their labs. We and our colleagues around the world spent much of our pandemic work-at-home time learning and sharing on online platforms, saving up the new knowledge to try out when we were back in our workspaces.

One of Williams’ goals when creating the ACBS was to make it freely available and customizable  – an open-design tool that could be built with readily available supplies and that could be adapted and improved upon by the conservation community through use and experimentation. Conservators at the Auckland War Memorial Museum in New Zealand took up this challenge and created an (also open access!) alternative design for the two clamps that sit at the top of the ACBS. The 3D-printed Auckland clamp design increases the range of motion of the fiberglass rods, adding even more functionality to the ACBS. (See their blog post: Newest Trick in the Book – Blog – Auckland War Memorial Museum (aucklandmuseum.com))

We wanted to build an ACBS for our lab, and we definitely wanted those clamps! We knew that KU Libraries had a 3D printer in our new Makerspace, so we reached out to Associate Librarian Tami Albin for her help. The Makerspace was in its early days, and Tami had been experimenting with the 3D printer, getting to know its capabilities and the properties of different filaments. We downloaded the files for the Auckland clamps and sent them to Tami. While Tami worked on the clamps, collections conservator Roberta Woodrick ordered the rest of the parts we needed for our ACBS’s (we had decided to build two), and she and I assembled them up to the point of adding the clamps. A few weeks later, Roberta and I visited the Makerspace to see the results of Tami’s first tests. Tami described how the 3D printer works, showed us the printed clamp parts, and explained how the type of filament affects the finished 3D print. She had printed an assortment of sample parts for us; we brought them back to the lab and examined each one to find those that had the look, feel, and weight that suited us, and to test the fit on the ACBS’s.

After we’d selected the samples that we liked best, we reported back to Tami and she set to work printing the final pieces. We were excited to get the email from her letting us know that the parts were ready! We gave Tami free rein to choose the filament colors, and she came through with a selection of bright, cheerful colors that add some fun and personality to our ACBS’s.

With the clamp parts in hand, we had a few more steps to go before the ABCS’s would be ready to use. I put together the clamp assembly and found that our off-the-shelf bolts were about 1mm too long, preventing the clamps from being fully tightened. I found my set of jeweler’s rasps (saved from a metals elective I took back in art school – conservators love to appropriate tools of many trades!) and used one to file down the ends of the bolts until they fit correctly.

With the clamps assembled, the last step was to fill in the sides of the ACBS’s to bring the surfaces level with the thick hinges. Per Williams’ instructions, I filled the lower boards of the ACBS’s with scraps of binder’s board, a heavier material, and the upper board with corrugated plastic, a lighter material, to help balance the ACBS. I then covered each side with blotter and sealed the edges all around with Tyvek tape.

Conservation is always a collaborative effort, and we are so grateful for Tami’s contribution to this project. We are looking forward to all the ways that we can put these new tools to use in our work caring for KU Libraries’ collections.

The Kenneth Spencer Research Library holds a rare 14th century Korean Buddhist sutra (MS D23) titled, Dae Bangwangbul Hwaeomgyeong (The Sutra of Garland Flower of Great Square and Broad World of Buddha). The sutra is the 45th volume of the eightieth version of the Avatamsaka Sutra translated by Siksananda between 695 and 699 in the Tang dynasty (Eung-Chon Choi, 2003). It is mounted in accordion book format, a practice commonly seen in China, Japan, and Korea (Hsin-Chen Tsai, 2017).

The sutra’s structure consists of papers with a width of 101 cm and height of 26.7 cm that are joined by one seam every nine pages with a starch-based adhesive[1]. The sutra has sixty-one pages of text comprising three chapters, and four pages on which is painted the frontispiece. The calligraphy and frontispiece are hand-painted in a metallic media, likely gold, where gold pigment is typically mixed with animal glue as the binding media (Hsin-Chem Tsai, 2017). The outer edges of the text block are also decorated in gold. The heads, chest, and hands of the three Buddhas in the frontispiece are further enhanced with cream, red, blue, and black opaque paint. The verso of the sutra is blank except for inscriptions along the seam of each join labeling each section.

There are four different papers observed throughout the sutra. The text block of the sutra is a double layer of dark blue dyed paper, likely indigo, that is highly burnished. The paper used on the verso of the frontispiece, back cover, and adjacent pages is a different laminated indigo paper. It is not burnished, and the indigo has prominent brush strokes (see Image 2). The paper cover has a white paper core consisting of a few sheets laminated together and is covered with a thin, blue paper. The front cover is decorated with flakes of gold leaf while the back blue paper cover is blank. Fiber identification characterized the furnish (fiber content) of these papers as a paper mulberry or a paper mulberry mixture with either mitsumata or gampi. These fibers are consistent with the known furnish of papers from this period and region.

According to Goryeo dynasty: Korea’s age of enlightenment, 918-1392, the following volumes from this set of Avatamsaka Sutra are extant and share the same style of calligraphy, treatment of the frontispiece, and cover design: Vol. 1 (private collection in Japan), Vol. 4 (Tokugawa Art Museum), Vols. 35 and 36 (Yamato Bunkakan), Vol. 42 (Tsaian-ji, Kobe), and Vol. 78 (The Cleveland Museum of Art). 

The sutra had several structural issues (weak folds, insect damage, old mends that were detaching) and was a priority for examination and treatment to stabilize it for future use. With great thanks to the Andrew W. Mellon Foundation and its support of a Collaborative Conservation Initiative at KU, there was allocated funding to host a visiting conservator to complete a special week-long project during the grant period. We reached out to Minah Song, a conservator in private practice in the Washington D.C. area, to advise on the development of a treatment plan for this rare object. Read more about Minah’s entire Visiting Conservator Project in the blog post written by Special Collections Conservator, Angela Andres.

After the sutra was examined and the condition issues prioritized, we shared our observations and treatment plan with Elspeth Healey, special collections librarian, who authorized the treatment. Our plan included addressing all necessary mending needs first. If we could tone a good matching paper, then we would also address the most visually distracting mends and overlays to reintegrate the paper margins of the sutra. We toned handmade Korean paper (hanji) using High Flow Golden acrylic paint (indigo/anthraquinone) and Dr. Ph. Martin’s Synchromatic Transparent watercolor (black) diluted with deionized water to mix various blue tones and achieve a good match with the sutra’s burnished indigo paper. The mixture was brush-applied to the hanji and the paper was hung to dry completely.

Once the paper was toned, we removed old mends across worm holes that were loose and detaching. We used the new mending paper to reinforce weak fold creases and replace old mends, as needed, and reattached the seams that were coming loose. The treatment overall was kept as minimal as possible with the primary goal of stabilization so that the sutra could be safely handled. Once the new mends and infills were attached with wheat starch paste, some were locally inpainted with Schminke watercolors to match the sutra’s paper tone more closely.

The conservation treatment of the sutra is now complete. The new mends have better visual integration with the object and allow for the sutra to be safely handled. We would like to extend our sincere thanks to Minah Song for her guidance and expertise on this important project. We would also like to thank Dr. Brian Atkinson, Assistant Professor in the Department of Ecology and Evolutionary Biology and Curator of the Division of Paleobotany at the Biodiversity Institute for the use of his microscope to complete fiber identification. Finally, we would like to thank the Andrew W. Mellon Foundation for enabling this collaboration.

In October, thanks to the efforts of Mellon Initiative conservator Jacinta Johnson, we realized a long-held dream of hosting a visiting conservator in our lab. Since we moved into this space three and a half years ago, we have been excited about the possibilities our new facility affords – from holding workshops to accommodating researchers, and much more. Of course, we’d barely gotten settled when the pandemic emerged and put these plans on hold. After a period of remote work, followed by returning to work full-time in the lab and getting accustomed to working within covid restrictions, we were ready to take the step of inviting an outside colleague to work with us for a week.

The grant that supports Jacinta’s work here at Spencer Research Library (SRL) and across Marvin Grove at the Spencer Museum of Art (SMA) includes funding to bring in visiting conservators to work on collections that have been identified as needing special attention. Jacinta arranged for Minah Song, a conservator working in private practice in the Washington, D.C. area, to spend a whole week in the lab. Much of Minah’s time here was spent working with Jacinta to examine, document, and explore treatment options for a rare Korean sutra housed in our special collections (MS D23). Minah also delivered a public lecture on the history and technology of Asian papermaking and its uses for conservation and held an information session on care and handling of Asian materials for SRL and SMA staff. In addition, Minah generously agreed to teach three mini-workshops for conservation lab staff and student employees. After such a long period of isolation and distancing, it was wonderful to interact with another conservator, step away from our routines, and learn something new.

For the first mini-workshop, Minah demonstrated friction drying, a method for flattening papers that may be sensitive to moisture or otherwise difficult to flatten, such as tracing paper. Jacinta has been treating drawings on tracing paper from the Mary Huntoon collections at both the SMA and SRL; she and Minah used two of these works to show how friction drying works. The drawings were first humidified in a Gore-Tex® stack, which allows water vapor to gently humidify the objects without direct contact with liquid water. Next the drawings were sandwiched between two sheets of lightly dampened mulberry paper and dried in a blotter stack under pressure for about a week. The process may need to be repeated for very stubborn creases. This method is a great, low-impact option for flattening notoriously fickle tracing paper.

In the next mini-workshop we learned how to do a double-sided lining for very brittle paper items, a technique that Minah perfected when she treated a large collection of fire-damaged documents. While this method should be considered a last option due the difficulty of fully reversing it, it can provide surprising stability for severely weakened papers while still allowing the text or images to be seen. (We used discarded newspaper clippings to practice on.) In this method, very thin kozo tissue is adhered to both sides of the item by applying very dilute wheat starch paste through a layer of Hollytex®, a nonwoven polyester material. The lined object is partially air-dried with the Hollytex® still attached, then dried in a stack overnight, at which point the Hollytex® is removed, and the object returned to the stack to fully dry. We were all surprised by the relative simplicity of the process, considering the fragility of the materials involved, and the results were impressive.

For our final mini-workshop, we had the chance to experiment with several types of pre-coated, solvent-set repair tissues. Pre-coated repair tissues usually consist of a thin kozo paper to which a layer of adhesive has been applied and allowed to dry. The coated paper can then be cut to size, reactivated with some type of solvent (usually water or ethanol), and applied to a tear to create a mend. We already use a pre-coated repair tissue prepared with a mixture of wheat starch paste and methycellulose, which is reactivated with water and serves as a good all-purpose repair material. But Minah demonstrated other types of pre-coated papers that offer other possible applications: tissue coated in Klucel™ M and reactivated with ethanol is a good option for documents containing iron gall inks or other water-sensitive media, and tissue coated with Aquazol®, reactivated with water, and set with a heated tacking iron can be an efficient choice for projects with a high volume of needed repairs, tight time constraints, or both.

We all greatly enjoyed our week working with and alongside Minah, getting to know her, and benefitting from her willingness to share her time and expertise with us. We now have a new conservation friend, and a wealth of new knowledge to bring to our work on KU’s collections.

Paul Springer, Jr., served as KU Libraries’ second HBCU Library Alliance Preservation Intern in the summer of 2021. He spent six weeks taking classes online with his cohort, who were each assigned to U.S. research libraries with conservation departments. He also worked with staff at Spencer Library to craft his own archival project. In this post, he describes his experiences.

My name is Paul Springer, a senior history and psychology major at Fisk University. My career aspirations involve me working with students and diversifying the academy. As an aspiring historian, I hope combine interdisciplinary studies to further African Diaspora studies. With interests in popular culture, U.S civil rights history, Nigeria, and a special focus on film, I hope to make connections between Nigerian popular culture and U.S social and civil rights movement in the 20^th century. I also wish to get involved with archival work dealing with popular culture materials. I believe that my particular skills could be useful in museums and libraries. Born and raised in Memphis, Tennessee, I hope to make impact in my community through historical research. As the home of the National Civil Rights Museum, my hometown has a prominent presence in African American research and heritage. Creating opportunities, engaging in community, and influencing the next generation are the most crucial components to any career path I choose.

Working with the Spencer Research Library at the University of Kansas, my project looks to collect documents, flyers, programs during the academic semesters that Covid-19 interrupted. So far, I have the written speeches of the Student Government Association president, a program for the Honors convocation, and photos from social media. Due to limited time during the internship, this project continues. My goal is to donate this collection to the Fisk University archives.

Over a year ago, I wrote about how working from home was going for me, about three months into the COVID19 pandemic. I was spending my time doing a lot of online professional development, attending Zoom meetings, interacting on social media, and working on small hands-on projects. 

Soon after that post was published, the Conservation Services team began our careful transition back to working on-site. In mid-June of 2020, I began going to the lab for a single 4-hour shift each week. Starting very slowly allowed us to establish safety practices and get a sense of our comfort level with in-person work at a time in the pandemic when it seemed there were still more questions than answers about how the virus was transmitted. We wore masks and put an extra focus on hand hygiene, and staggered our lab shifts to reduce the number of people working at a time. Our large lab space also made it possible to keep a safe distance from one another. Even with all the uncertainty, I was grateful not only to still have my job, but to be back in the lab, working directly with the collections once again.

The following month, I increased my lab time to four 4-hour shifts per week, and maintained that schedule through the rest of 2020. I continued my professional development activities during work-at-home time, attending hundreds of hours worth of webinars and lectures, in addition to lots of reading. The annual meeting of the American Institute for Conservation (AIC) was held completely online last year, so I was able to attend many more presentations at this conference than I would have if it were held in person. In addition, I filled much of my at-home time from September through December working on an online Chemistry for Conservators course.

In January 2021, I added a fifth 4-hour shift to my schedule, bringing my lab time to 20 hours per week. At-home time continued to be filled with emails, meetings, lots of reading, and more online professional development, including another virtual AIC annual meeting. Then, in May, I moved to working four full days in the lab and one day at home per week. The types of activities I do at home are the same, I’m just doing less of them – and I’m so happy to be working in the lab more. It’s very satisfying to be filling my log sheets with treatment records, and to see my production statistics adding up again. For reference, here’s a comparison of my second quarter statistics from 2019, 2020, and 2021. I was able to complete a small number of treatments after our part-time return toward the end of June 2020, but my 2021 numbers are much closer to normal – a welcome and hopeful development.

While questions remain about what the fall semester will look like this year, and the pandemic is not over by any measure, the experience of the last 15 months has shown that it’s possible to adapt conservation work to extraordinary circumstances. Now that I’m back in the lab nearly full-time, I have a new appreciation for the privilege of being able to do this work, and especially for the people I work with and the supportive environment that they create in our workplace.
