A Simple Solution for Lantern Slides

By Lisa | April 19, 2016 | Comments 0 Comment

This October the Preservation Lab arranged for staff training in photograph conservation with an expert in this specialty to help us address specific needs for the two institutions. The lab hosted a 3-day workshop taught by Photograph Conservator, Tom Edmondson. Lab staff and two other local paper and book conservators attended. We were taught how to identify more than 16 types of historic photographic processes. We learned how to safely preserve and store a variety of formats, including daguerreotypes and lantern slides. Using actual historical photographs as learning opportunities we were taught basic and advanced treatment techniques such as surface cleaning photographs, washing, removing linings, flattening creases, and matting. The technicians have already begun to implement the knowledge gleaned from the workshop in the treatment of some Public Library lantern slides.
For example, with the lantern slide below the losses on the glass were filled with Vivak in order to prevent further damage. Vivak, a clear thermoplastic sheet, was chosen since it is archival, looks similar to glass and is an easy material to cut and shape without losing its structural integrity.
The Vivak was precisely cut and placed onto the missing areas.

Collage3 — Detailed images of the Vivak fills. Verso and recto pieces were secured together with a strip of Filmoplast R.

To attach the recto and verso of the Vivak fill pieces to each other, a strip of Filmoplast R was used around the edges. Filmoplast R, a cellulose tissue coated with an acid and solvent free heat-activated adhesive, was toned with Golden fluid acrylics to match the original paper strip around the edges of the lantern slide.
To protect the edges of the lantern slide, and to secure the filled areas in place, a strip of Mylar (polyester film) was placed along the edges and secured with a small piece of Filmoplast R.

The strip of Mylar around the edges of the lantern slide will also work as a barrier between the edges of the original object and Filmoplast R adhesive.

Finally, the lantern slide was sandwiched between two pieces of Vivak and secured with a strip of toned Filmoplast R by wrapping it around the edges.

With another lantern slide, the original plastic coated paper strip around the glass plates was lifting and detaching from the glass.

The detached black strip was mended and adhered in place with the heat activated adhesive BEVA film 371, and a tacking iron.

Since this lantern slide was not broken and the paper was mended, there was no need to sandwich the lantern slide between pieces of Vivak.

This project was a great opportunity to learn and work with different materials.

Loopy

By Lisa | March 24, 2016 | Comments 0 Comment

Some small booklets from the 1820s recently came to the Lab to be cleaned and prepared for digitization at the Public Library of Cincinnati and Hamilton County. Ashleigh, our Conservator, noticed a couple of them had a small loop of string attached in the upper left hand corner.

Well, the booklets are all copies of “Freeman’s Almanack”. Before the days of smart phone calendars and weather apps, before the days of catching the weather on the radio or TV, people had almanacs. In fact some people still use them today, though these days their scope has expanded and some of them can be many hundreds of pages, depending on the information they contain. Back in the 1800s they usually looked like small magazines. Published yearly, they contained articles and snippets of wit and wisdom the publishers thought their target audience (often farmers) might enjoy. Most important though were the tables, usually organized to represent a calendar month, giving times for sunrise and sunset, astronomical highlights such as eclipses, church festivals, planting dates, and what kind of weather to expect.
So what about the loops?
Well, the almanac would be something a 19^th Century family might refer to often, perhaps even daily. Where do you put such a thing in your home so everyone can grab it quickly when they need it? You hang it on a nail of course! How do you do that? You make a little hole in the top left corner of the booklet, you run some string or thread through the hole to make a loop, and you pop the loop over the nail.

Problem (and mystery) solved!

Prepping for a Shift

By Lisa | March 11, 2016 | Comments 0 Comment

Stack shifts and moves are an inevitability in libraries. Collections change. Spaces change, more often than not becoming too small for the collection(s). And in the end a shift of collections is imminent. For most collections these stack shifts do not require the intervention of a conservation lab. Periodical bindings moving to another floor? It happens all the time and that’s that. But when special collection items are shifted or moved, the Preservation Lab generally plays a part. So when UC’s Archives and Rare Books Library decided to move and shift the bulk of their oversized special collections between stack levels the Lab was contacted to play a part in the prep work.
The plan? To measure and box as many unstable or unwieldy oversized books that will be moving between floors or shifting within narrow, restrictive shelving stacks before the move in April. In order to keep our current workflow of treatments (both general circulating and special collections) for both institutions going, it was decided that a couple of lab staff would measure the books on-site (ARB Library), have corrugated enclosures created through our commercial bindery vendor, and then as the boxes were received the staff would match up the books with the boxes. Three staff members, Holly Prochaska (librarian), Veronica Sorcher (technician), and myself, took on the duty of assessing the books and taking measurements for those we felt could easily hinder the move or be damaged further by handling and moving.

MeasuringSetup — Measuring in the stacks and making do with the space you have.

At this point we are about half way through the process. We’ve measured over 750 books for enclosures! We enlisted one of our trusty student assistants to record all the data so that we could send it off to the commercial binder. The first batch of 150 boxes arrived and were matched up with the books earlier this week. And luckily, our error rate was actually very low, even with that first batch where we were still figuring out the kinks of measuring in confined spaces and often dim lighting!
What’s the workflow like? Each person has list of numbers that correspond to the number the binder prints on the inside of the enclosure, per our request. For each number, the staff member records the call number (to be printed on the spine of the box), along with the height, width and thickness of the book. A flag with that number written on it (in pencil, of course) is then placed in the book so that it is visible on the shelf and clearly recognizable when matching the boxes to the books. So far, the process has worked pretty well.
What kinds of things are we prepping for storage and handling? Prime candidates for move-prep housing include…

Any book previously tied with cotton tying tape, usually to hold a detached/loose board or textblock in place.

In this case, boards were detached from the spine/textblock. But let’s just talk about the reason I really took a photo of this book on Christopher Columbus…the anchor clasps and catches! How cool are those?

Any book with loose, detached, or protruding parts that could be abraded, damaged further, or lost during the move.

When I originally pulled this book off the shelf the measure it the corner was nowhere to be found, but I found it a couple shelves down resting on top of another book.

Any extremely fragile or flimsy books, including extremely oversized, thin bindings or bindings with fragile paper or degraded leather covers.

This full leather binding must have been fire damaged at some point. The leather on the spine was so fragile and would crack and break if you looked at it the wrong way.

The evil monster known as RED ROT!

Obviously not all books with red rot were boxed, especially those with very minor cases. But books like this, where the movers and every book in the surrounding area would be covered in a red layer of degraded leather…those get boxes!

Tiny Tomes – Now on Display!

By Lisa | January 20, 2016 | Comments 0 Comment

There’s an exciting new Public Library exhibit located in the Popular Library in the Main Library building downtown. It’s titled, Tiny Tomes and includes over 50 small books that are part of the reference library collection. There are a variety of subjects, binding styles, and time periods represented. Topics include sport flip books, lichens & ferns, children’s books, and many more!
This past week, the Preservation Lab assisted with preparing the books for display. Once the layout of the show was established and pages were selected for display, I helped strap bindings with soft polyethylene strapping and showed staff how to use various supports made out of Vivak and archival mat board. These supports were made beforehand in our lab by lab technician, Chris Voynovich. Since we knew the overall size of the books were generally 4 x 6 inches, a variety of general supports were constructed out of lab scraps rather than custom fitting the supports to each book. This greatly expedited the process of making the book cradles.
Out of approximately 40 constructed supports, every single one was put to use! There were V-shaped supports used to hold books open while lying flat, U-shaped supports to lift up books, triangle shaped supports to act as cradles, and other supports to hold books safely upright.

Some books were too fragile to be opened or had more than one page to exhibit. As an alternative to displaying interior pages, some of the books were scanned by Digital Services and surrogates were printed. These images are also available online, located here: http://cdm16998.contentdm.oclc.org/cdm/landingpage/collection/p16998coll52.
The exhibit runs from Jan 18^th to March 13^st. While you’re at Main Library, be sure to check out the Smallest Book on exhibit in the Cincinnati Room, located on the 3^rd floor!

Mounting a Microscopic Book

By Lisa | December 17, 2015 | Comments 0 Comment

One of the treasures I was recently asked to prepare for display was a book called The Smallest Book in the World. The library owns two copies printed by German typographer, Josua Reichert. The tiny book contains typography that was uniquely designed specifically for the binding. Each page contains a CMYK colored alphabet letter in an exquisitely designed font. While not currently the smallest book in the world, it is probably the smallest traditionally printed edition!

Paper making in the lab

By Lisa | December 8, 2015 | Comments 0 Comment

In April the Provost Office awarded the lab funds to purchase paper making equipment through the Third Century Faculty Research Materials Grant. Over the next six months the lab intends to establish a workflow for paper making so that we may begin producing our own archival quality papers for conservation treatments. With the grant monies we purchased a Hollander beater in July, and yesterday the other pivotal piece of equipment arrived, a hydraulic press. The beater masticates fibers, that with water, create a fiber slurry that is poured into a mould. Each mould forms a single sheet of paper that is then pressed to remove the excess water – further bonding the fibers and creating a smooth surface.
More information as we begin our experimentation!

Our hydraulic press was made specifically for the lab by our amazing UC carpenters

Custom Collapsible Cradle in a Corrugated Box!

By Lisa | November 9, 2015 | Comments 0 Comment

We have many occasions to use cradles. Including, in the lab while working on delicate materials and for viewing the text of fragile bindings. In an effort to create a new standard for the lab to store with a book, I revisited the construction of a collapsible cradle that fits inside a corrugated clamshell box.

View of clamshell when lid is opened:

Opening the cradle by lifting the cloth tapes:

Obtuse (left) and acute (right) arm openings are adjustable:

The integral cradle is removable for display!

I am intrigued by this integral cradle system for a few important reasons:

The cradle is custom fit for the individual book’s opening and is stored safely with the book in the corrugated clamshell so it won’t become lost.
The cradle can be made adjustable to accommodate the book’s special handling needs by adding in additional notches.
The cradle has a base, making it removable from the box. This enables diversity in placement of the supported book. For example, librarians can remove the cradle from the box for exhibition.
This system is light, yet durable.
This system is fast and easy to create.
This system can be shelved with other books making it easily stored and accessible.

Considering all the cradles I have made so far, this one is by far the easiest and fastest to complete!
For a “one size fits all” solution, check out our blog on Elizabeth’s Rideout’s Collapsible Book Cradle.
It has been fun to explore solutions for this support mechanism to strengthen our arsenal of weaponry in the war of conservation!

We love artists' books: the finished boxes!

By Lisa | October 29, 2015 | Comments 0 Comment

You may recall that back in July I blogged about these two beauties that came to the Lab for custom enclosures. They both returned to PLCH at the beginning of September in their custom enclosures, so I thought I’d share what type of enclosures we came up with to address all the fragile elements of these particular artists’ books. …

Frankenscores!

Score!

By Lisa | August 12, 2015 | Comments 0 Comment

The Public Library of Cincinnati and Hamilton County has recently set a plan in motion to digitize a collection of music scores. But before they can be digitized, the scores need to cataloged at the item level so metadata can be added to the digital files that are uploaded to the Virtual Public Library. But first, they are traveling to the lab to receive stabilization, to improve legibility, and rehousing. There are more than 200 boxes in the collection, each containing fifty or more scores, so this will be an ongoing project for many months to come. Because there are so many, and the Library would like to have them digitized as soon as possible, the decision was made to keep the treatments minimal –enough to stabilize the materials and render them more legible but no more.
