Kenneth Spencer Research Library

Taking our cue from a 2009 Conserve-O-Gram (a free resource published by the National Park Service) titled “Flag Rolling and Storage,” staff in Conservation Services created an inexpensive and accessible textile storage system. The University of Kansas class and school banners are part of the collection materials found in University Archives. These banners are an important part of the history of the commencement ceremony at the university. The banners are visually interesting and also instructive artifacts as markers of KU’s changing awareness of brand identity.

After photographing each banner, staff carefully rolled each item around an pH-neutral cardboard core.

The rolling process began with a tissue paper-liner and ended with a cover of cotton muslin. Each cover was tied into place just beyond the edges of the banner and identified with a small tag showing an image of the item inside as well as its call number.

There are several advantages to rolling textiles for long-term storage. There are no folds made in the fabric, reducing stress on the fibers and limiting the creation of breaks and tears. Each textile can be removed independently of the others (unlike housing several textiles in a single box) thus decreasing the number of times all the objects must be handled. And because hanging storage is vertically oriented, it takes up less space than shelves or drawers, and can be fitted on an unused wall or into an aisle.

Once staff completed the rolling process, empty shelves were removed from two ranges in the Spencer stacks. A durable, link-style chain was suspended from the overhead shelving beams and secured into place using locking bolts. Metal electrical conduit was cut to the proper length and passed through the center of the cardboard tubes. S-hooks were hung at intervals along the chain to support the rolls.  The resulting storage has a slim profile, and provides quick and easy access to the collection materials.

An unused stretch of wall space on the first floor of Spencer has become the new home to about fifty paintings formerly housed in the Kansas Collection and University Archives stacks. Following a visit to the collection storage area at the Spencer Museum of Art, Conservation Services staff installed a similar gridwall panel system.

The panels are much like ones found in retail stores for displaying merchandise. They come in a variety of lengths and widths, which make them very adaptable to the existing environment in which they are placed. The walls on which the panels were mounted were a bit less cooperative, as evidenced by the number and wear on the bits used in drilling process.

Staff first attached painted wooden boards to the wall to reinforce the plaster surface. This also ensured that the hooks used for hanging the gridwall panels could be accurately fixed in place.

Once the installation was complete, staff fastened d-ring hangers with short, pan-head wood screws to the frames or stretcher bars on the verso of the paintings. Although a few of the paintings were already equipped with hooks and wires, it was deemed more secure and stable to use the d-ring hangers for hanging on the panels. The use of a d-ring on each side of the frame/stretcher bar allows the painting to be hung from a pair of hooks. In this manner, the painting will not slide from side to side as it would when hung on a wire over a single hanger.

The paintings were then arranged salon-style, using the panel space as efficiently as possible. The paintings are now much easier to page for patrons. This is also a better storage environment for the items, as they are no longer standing on one side of their frame/stretcher bar or resting against one another.

As a final preservation strategy, the paintings have been draped in Tyvek. This material, best known for its application in house construction, is an excellent, light-weight covering to protect the paintings from dust and abrasion. In addition, we created a visual map of all the paintings to aid in paging them for patrons with the least disruption to the Tyvek drapery.

November is bringing good news for the storage conditions for many oversized, flat items in the Kansas Collection. After much planning and pondering, the existing wooden “cubby” storage unit has been dismantled to make way for flat file storage drawers often referred to as map cases.

Over time, paintings, other framed materials, and oversized architectural drawings had ended up in the cubbies for lack of a more suitable place to store these challengingly-shaped and often very large items.

Student employees and staff worked to clear collections from the wooden storage unit. Some of the materials will return to the newly installed map cases, while others have moved to an area specifically made for hanging paintings and framed objects. Conservation Services staff then took apart the cubbies using car jacks, pry bars, and a sledge hammer. The original structure of the cubbies relied heavily on a slot-in-tab method of construction which made for a smoother deconstruction than if the unit had been held together primarily with screws or nails.

In a happy bit of up-cycling, a sculpture professor in the Art Department at KU collected the nearly 50-year old ply board to be used by students working in the Fine Arts and Design Schools. Facilities Operations staff leveled the area by installing tile over the bare concrete floor and then installed fifteen five-drawer sets of map cases.

New map cases for flat storage

Over the coming months, oversized and flat material–housed in appropriately-sized folders–will be placed in the new cases. This will not only provide a better storage environment for the items, it will also make the materials easier to page for patron use.

One of the jobs of Conservation Services is to ensure that the storage spaces in Spencer Research Library are suitable for  collections materials. We have placed thirteen dataloggers–plastic boxes smaller than the side of a credit card–around Spencer Library to take readings of temperature and relative humidity at thirty-minute intervals.

The information is analyzed in a special software, called Climate Notebook, and the graphs are stored in a central location on KU Libraries’ network so various library staff members can watch for unusual changes in their spaces.

If paper-based materials become too hot and humid, mold could flourish and damage collections. If a storage space is too dry and hot, embrittlement of organic collection materials like paper and textiles could result. Generally, the lower the temperature, the better for our library collections, but because these collections occupy the same space as people, we’ve set a compromised standard of around 70 degrees Fahrenheit and 50% relative humidity.

Some Spencer collections are stored in KU Libraries’ high-density storage facility, which is kept at around 50 degrees F and 35% relative humidity. In such a space, materials will last longer as rates of deterioration are slowed.

Soon, Spencer Library will unveil its latest exhibition, on the work of John Gould and his atelier. Conservation Services staff support exhibition design by helping the curators present the items in their best light. For bound volumes this work often involves the construction of a supportive cradle.

Many library conservation labs construct cradles and supports from Vivak, a transparent, cold-bendable, PETG plastic. Unlike the more traditional Plexiglas, Vivak can be cut on our board shear (no scoring required).

Once the sheet is cut, the locations for bending are transferred from a paper template to the Vivak sheet. Vivak comes with a protective plastic film that is left in place until the final installation to prevent scratching of the soft plastic.

The plastic can be bent by hand, but we use a sheet metal bender to make the process easier. Plexiglas requires heat to bend, so we are happy to avoid that step and the accompanying fumes that result. Making cradles with Vivak is much quicker and less toxic.

Vivak is not as sturdy as the Plexiglas we used to use, but if stored properly cradles can be reused for multiple exhibits.
