Problem Solving: An Exhibition-Style Enclosure for a Collection of Lafcadio Hearn Japanese Bindings

This set of Japanese side-sewn, crepe paper bindings, or Chirimen-bon, came to the Preservation Lab housed in their damaged traditional Japanese wraparound case, known as a maru chitsu. The set belongs to the Cincinnati and Hamilton County Public Library, which has an extensive Lafcadio Hearn collection. This collection of volumes was printed by Hasegawa Takejirō, a Japanese publisher who specialized in books written in European languages on Japanese subjects. The Japanese Fairy Tale Series was one of the more popular series, beginning with six volumes in 1885; though this later collection only has five volumes of fairy tales. Lacadio Hearn was one of the foreign translators employed by T. Hasegawa.

Due to the high profile nature of Lafcadio Hearn for the library and the beauty of the bindings, the collection is often shown during tours and used for display, however, the crepe paper volumes, while in excellent condition, are extremely floppy, and they are also side-sewn, both factors make them difficult to handle and display. The original enclosure is also very fragile and damaged, and susceptible to further damage if used as an enclosure moving forward. For all these reasons, the curators wanted an enclosure that would not only store the collection long-term, but could also be used for display.

This proved to be a challenge, but a fun one. I started by making a couple of sketches and then a couple of models…

Three models pictured, two are collapsible cradles and one display stand with foam insert — Models – two types of collapsible cradles and one model of the display tray/stand

For the models, I had two main focuses: 1) a collapsible cradle that would house and display one of the volumes, and 2) a display component that would act as a tray or level within the enclosure and house the remaining four volumes, in two stacks of two, side by side.

I will always advocate for making a model if you are trying to work through a new enclosure or adjust an existing enclosure or display piece, like a cradle. For example, I knew that a normal collapsible cradle wasn’t going to fit the bill for these volumes. Instead, I was going to need a stiff, squared off spine piece built into the cradle to help support the bindings’ spines.

One of the main areas I had to troubleshoot was the display tray, which would house the four remaining volumes. I knew I wanted to create a stand that would basically replicate one side of a collapsible cradle and have a 1/2 inch Plastazote foam insert, which happened to nestle the thickness of two volumes perfectly, that was covered in Tyvek. But I had concerns about gravity and reliability of PVA to hold the foam insert in place overtime. And I wasn’t happy with my initial ideas of how to remove the volumes (and also the original enclosure and collapsible cradle) from the insert(s), which consisted of a tab underneath the volume. It created friction that would ultimately cause damage to the actual volumes.

Ultimately, I am extremely happy with what I came up with. I think it functions very well, and checks all the boxes it needed to check. Safe, secure storage. Elegant display. User-friendly.

The display stand includes a cloth tape inserted into the boards to keep it from opening too far, a foam insert covered in Tyvek, a lip to support the foam insert overtime, and two polyester film slings to aid in removing the volumes from the foam insert. The polyester slings proved to be an excellent solution for removing all the elements from the enclosure safely and easily.

For those interested in how some of the components were constructed, here are some in-progress images…

Because of the way the trays/components of the enclosure are constructed, they are actually interchangeable. So if the “lower tray” with the original enclosure and collapsible cradle ends up on top of the display tray/stand, that’s not an issue at all. And there is a 1/4 inch Volara foam piece adhered to the outer tray of the clamshell enclosure, so whatever items are on top will be cushioned by soft foam in the enclosure.

A librarian’s new favorite teaching tool? A historical book model!

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 15^th 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.

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:

Text block

Primary support – Khadi paper white cotton rag
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).

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 15^th century bookbinding, and this would provide the students with the experience of handling a book with clasps and allow them to understand their function.

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.

Working with Abe

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.
