Shrink-wrap, a tool in the toolbox

The Preservation Lab is lucky to have a lot of equipment.  One of our more interesting pieces is a shrink-wrap machine.  We bring the machine out about once a year when we have a fair amount of bound materials that meet the following criteria:

  • part of the general circulating collection;
  • an item with a history of little or low use;
  • brittle paper, making rebinding or repair impossible or too time consuming;
  • replacements are not available or prohibitively expensive considering use.

Before the retirement of Pat Schmude, a UCL conservation technician in the lab for 28 years, we brought the machine up so that he could remind us of all the special things we need to do to make it work optimally — all the things you just don’t find in a manual but you know from 20+ years experience.
And of course we did have a little fun…here is my coffee mug shrink-wrapped.  I’m trying to give it up…so far I haven’t broken the seal!

Preservation Week 2015!

Demonstration CollageWe love preservation. Of course we do. And as people who love preservation, we naturally love Preservation Week! Truly, we do. We love it so much that we take to the streets and invite people over to share it with us. We were so excited that we decided to start early this year, with live technical demonstrations in the mornings leading up to the big day. We wanted people to see what we were up to, ask lots of questions, and learn more about what we do.
We showed off the past year’s work, including some excellent pieces done by our pre-program volunteer, Catarina Figueirinhas. Everyone’s favorite, the hot stamper, made a return appearance. We topped off the festivities with a raffle for a book, handmade by one of our students, and of course, cookies (we don’t have open houses for the sweets, but they are a nice bonus!).  We had such a great time with all of our friends and colleagues, and as always, we look forward to doing it again next year.

Preservation Exhibit

One of the perks of being on UC Libraries’ Exhibits Committee, besides working with a fantastic group of people, is being able to share and promote the interesting things we are doing here in the Lab. The most recent exhibit I curated for the committee is entitled “Preserving the Past for the Future” and showcases a variety of UCL and PLCH special collection materials that have been treated in the Lab over the last year and a half. As the conservation technician who performs the bulk of the photo documentation for the Lab, I thought sharing these “before”, “after” and often “during” photos alongside the information about the treatments would make this exhibit more visually descriptive for the public, who are primarily UC students. This exhibit, which was so beautifully brought to life by Melissa Cox Norris, director of library communications, and Amanda Jackson, former communications co-op design student, is displayed on the 5th floor of Langsam Library and the full online exhibit created by Lisa Haitz, web developer, can be viewed via LiBlog at https://libapps.libraries.uc.edu/liblog/2015/04/preservation-exhibit/. I hope you get a chance to check it out and enjoy seeing a little bit of what we do here in the Preservation Lab.

Housing the Public Library's historic stained glass

When the original Main Library at 629 Vine Street opened to the public in 1873, three beautiful and intricate stained glass windows graced one of the reading rooms in the building. In 1955, when the building was demolished, the windows were sold at auction, later to resurface as part of the decor of the Old Spaghetti Factory on Pete Rose Way. After the restaurant closed to make room for Paul Brown Stadium, the Library purchased the windows and began making plans to return them to the Main Library for the appreciation and enjoyment of our customers and staff. Thanks to the generosity of the Friends and the Annabel Fey Trust Fund, the three windows have now been re-created and restored to their original glory and will be on permanent display in the Main Library.

18th and 19th century leather: A Conservation Challenge!

If you’ve ever had the pleasure of handling special collection materials, you may have noticed that some books stand the test of time better than others.
In particular, why is it that some older leather books that date to the 15th century still function well, while other leather covered books from the 1700’s and 1800’s fall apart and turn to powder in our hands?
The reason is twofold. Books made in the Carolingian, Romanesque and Gothic periods were highly engineered luxury items that were made with high quality materials. Later, as books become more of a household commodity, quality was sacrificed to meet rising production needs, leading to books being made cheaply with poor quality materials. The common degradation we find in 18th and 19th century tightback leather bindings is a direct result of poor construction combined with the use of poor quality materials.
What exactly is causing this later leather to degrade? There are many reasons such as environmental factors, but two of the most common condition issues are caused by the type of animal skin used, and the materials used to tan the leather.
For example, sheepskin leather exhibits characteristic degradation of shearing away in layers while calfskin does not. This is essentially because sheep have a thicker undercoat of fur. The roots of the sheep’s undercoat grow in-between the lower corium and upper grain layers of the skin, and after the hair is removed during the tanning process, a microscopic void is left between the layers of skin. As a result, the leather becomes vulnerable to delamination overtime (see photo below).

Rolling out Elizabeth Rideout’s collapsible book cradle

Last month our lab hosted a little workshop, taught by talented conservation technician, Chris Voynovich (PLCH), on collapsible book cradles. The workshop came about after our conservator shared images of Elizabeth Rideout’s collapsible book cradle with us and explained how beneficial this would be for the special collections holding libraries to have cradles like this on hand. Chris, who is usually the go-to technician in the lab for tricky enclosures, jumped at the opportunity to create a cradle. So without any instructions available he made a collapsible, adjustable cradle based on the images of Rideout’s cradle online. Chris then wrote up some instructions for a standard size cradle that fits most books. With the instructions on hand we went ahead and planned the workshop, inviting colleagues from both UCL and PLCH.

Saving the 70's

Recently I’ve had the opportunity to dis-bind a bound edition of our school newspaper, send it off for digitization and then to create a clamshell box to house the single pages when they return. The process of dis-binding bound newspapers is a very delicate one. In this case, The News Record 1971-72, was no exception. Newspapers, by their very nature are meant to be read and thrown away. The paper they are printed on is not meant to last and it fades and becomes acidic and brittle very rapidly. The solution to preserving the paper’s information back in the early 70’s, before digitization was even a thought, was to bind a couple years’ worth of the News Record together in a hard cover much like a large book. This was a good method for preserving a piece of U.C.’s history, however the binding was meant to be permanent and no thought was given to reversing the process at a later date.
