Exhibit Standards

Exhibits are great way for libraries to raise awareness about the gems in their collections.  An exhibit can showcase a little known collection of letters or highlight specific details within a well known story.

Exhibits can also be a lot of work, it is hard to pull together the right set of documents to tell a story and then write concise yet informative labels that bring everything together.  Displaying collections is also trickier than it seems.  You want to be certain that your exhibit area has good, stable environmental conditions in terms of temperature, relative humidity and lighting.  You want to be sure the cases seal so that the objects are free from dust and tampering.  There are a lot of details to address, but the good news is that there are standards available to help anyone involved in the exhibit process. 

The National Information Standards Organization publishes free technical leaflets, including "Environmental Conditions for Exhibiting Library & Archival Materials" [Z39.79-2001] which is available as a free, downloadable pdf. from their website.  The link to the pdf. is in the lower left corner of the linked NISO page.  These standards can be particularly useful for those who do not have a conservator or exhibits preparator on staff.

One commonly overlooked detail is a backing board for paper documents.  Many institutions re-use Plexiglas cradles from one exhibit to the next, and this makes a certain amount of sense as it eliminates waste and saves money.  Of course, paper documents come in many different sizes, so a cradle from a previous exhibit will often have to be modified.  Take a look at the picture below, and see how the document is taller and wider than the Plexiglas.  This may not seem like a significant amount, but this is 400 year old paper that has seen a bit of wear and tear over the years and if left on display without proper support, the letter could start to curl and droop over the edge of the Plexiglas cradle.  Why take that chance?

see how much the document hangs over on the left and at the top?

All that you need to do is take a piece of archival mat board and trim it so that it is just a few millimeters longer and wider than the original document, and then strap the document to it with polystrap so that it doesn't shift while you're opening and closing the exhibit case.  This is very easy to do and will make a tremendous difference in the long term preservation of your collections.

Chapter 8 of the NISO standard has all the basics for safe display of flat paper items, and the rest of the document has very useful information for bound volumes, lighting, etc.  So go ahead, check it out!

Not Too "Matchy-Matchy"

Conservation treatment is not about recreating the original artifact, and there is no way to really turn back the clock to make an old, well-used book look new.  As I have mentioned in my posts about treating Micrgraphia or Il Quattro Libri de'll Archittetura sometimes there is not enough of the original binding to do anything but make an educated guess as to what the original binding might have been.

One of the books I'm working on now is Thomas Jefferson's 1825 catalog of books for the UVa Library, his "shopping list" that was used to create the University's first library.  The book is actually two signatures from what must have been a larger blank journal.  At some point (probably in the early 20th century) the signatures were sewn into a new binding with blank pages at the beginning and the end to bulk out the text block and a new cover of leather and marbled paper.  It probably looked really spiffy back in the day, but the "new" binding did not have nearly the strength or archival soundness of the handmade paper from Jefferson's day.  By the time I saw the book, the added blank pages were falling out and the front cover was starting to detach from the binding.

several Poe signatures!

Binding a thin book can be very tricky, but I think I've come up with a structure that works, so then the question becomes how do I want the final binding to look?  Where does this catalog fit in to our Library collection?  Since I am confident that the original signatures were once part of a blank book and I know that Charlottesville had at least one stationer (seller of blank books and stationery) in business in the 1820's, Ebenezer Watts, I was at first thinking I'd do another reverse-calf binding like I'd done for the First Minute Book.  However, I looked through the Library's archival collection of record books from the early days of UVa and noticed that a number of the record books were simple reverse calf spines with marbled paper over the boards.  So I decided that I would model the binding on the first circulation book for the library. 

The library staff agreed with my concept, so then I had to track down period-appropriate marbled paper to cover the boards, which is not as easy as it sounds.  There are many different styles of marbled paper and the brightly colored, combed and fanned types are much more popular today. But the good news is that that there are almost as many marbling nerds out there as book nerds and I was able to find a paper that fit the time period.  The vendor offered to match any one of the marbled papers in our collection, but I didn't want it match so much as "fit in". 

Given these examples:

 

I received these two papers:

 I've placed them next to the leather I plan to use for the reverse goat spine.  I like the one on the left, what do you think?  Tune in next month for pictures of the finished product!

 

Cool Books

I often go into the stacks to review the condition of a book that is showing signs of wear and tear, but every now and then I take a little time to look at books that are just plain cool.

Cosmographia Petri Apiani [A 1550 .A75a]

This is Cosmographia Petri Apiani, printed in Antwerp in 1550 despite the date inscribed on the cover.  It caught my eye because of the alum tawed hide which is a lovely golden color.  You can really see the hair follicle pattern in the hide and the blind tooling is really nice.  It is a small book, only 23.5 cm x 17 cm and is in remarkably good condition.

The book contains astronomical observations, and charts and tools to make your own observations. This volvelle is one of the tools you can use.  It is in it's original condition, with the different wheels and central fastener still in working order.

This hand colored map is just gorgeous. 

But my favorite image is this one which shows the earth in the center and the sun "solis" as the fourth planet!

Desiccant Wheels

As a book conservator I was trained to dis-bind, wash, mend and re-sew books from different points in history.  However, a library's storage environment also plays a crucial role in the longevity of collections.  There's little to be gained from spending hours and hours treating a rare book if you have to send it back to a stacks area that is not up to par.
 
Facilities staff will always have the primary responsibility for maintaining the air handling systems, but it is important that librarians are engaged and articulate about the systems that take care of their books.  So a significant portion of my training focused on building systems, including heating, ventilating and air-conditioning (HVAC).  We had a final workshop on HVAC systems that reviewed different types of HVAC technology and concluded with a walk through of the air handlers in our classroom building. 

One of the technologies that was new at the time (1998) was using a desiccant wheel for de-humidification.  Have you noticed the little silica packets that come in boxes of shoes or electronics?  They're like that but much, much bigger.   

All of the buildings I've worked in 'til now have been older buildings with older types of HVAC systems.  My current job has been my first opportunity to see a desiccant wheel up close and I must say it was pretty exciting.  You can gete a sense of how big the wheel is from the picture above.  The yellow strap is the drive belt for the wheel, to keep it turning so that the unsaturated section of the wheel is in the airflow from the building while the saturated part is getting dried out. 

The wheels do get changed when they wear out as you can see below.  They're very, very heavy, so it is a good thing they roll.

Mathew Brady's Civil War photographs

Mathew Brady is probably the most famous photographer associated with the American Civil War.  The UVa Small Special Collections Library has a small collection of the photos, mounted on individual cards.

The photos are kept in climate controlled storage, but the box they were in was a little too big and allowed the photos to warp.

Not good.  But fixable!
First, the photographs are humidified between two layers of Gortex, to relax both the cardboard and photograph layer.

Then it is time for my old favorite technique, the "back and wrap" which is great for stabilizing individual items.  The flattened photograph is placed on a piece of mat board that is slightly larger.  Since each photograph is labeled on the back with the number and title of the photograph, plus Brady's copyright warning, I photocopied the backs of the photographs, cut out the labels and adhered them to the back of the mat board.  I also wrote the call number on each one.

The photo and mat board are placed face down on a piece of Mylar and the corners of the Mylar are trimmed away. 

The Mylar is wrapped around the edges of the board and secured with double stick tape.  A neat package that buffers the photograph from environmental shifts, provides enough stiffness to keep the cardboard from warping, and the Mylar protects the photograph from scratches, fingerprints and dust.

A neat little package that makes it possible to handle the photographs more safely!
