Score!

Score!

By | | 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.

Shrink-wrap, a tool in the toolbox

Shrink-wrap, a tool in the toolbox

By | | Comments 0 Comment

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!

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.

Rolling out Elizabeth Rideout’s collapsible book cradle

Rolling out Elizabeth Rideout’s collapsible book cradle

By | | Comments 0 Comment

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

Saving the 70's

By | | Comments 0 Comment

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.

The Collapsible Book Cradle

The Collapsible Book Cradle

I love to design and make things work! Recently I have had the opportunity to kick around a new contraption for displaying or otherwise supporting books, the collapsible book cradle.
These guys are handy for keeping a book stable for viewing which greatly reduces the wear and tear on the object through excessive handling. The cradle is also useful as a support for a book in delicate condition for the conservator or tech to perform repairs.
This particular cradle design also has the feature to collapse to a book like shape which can be stored on the book shelf next to the other books when not in use. Thus the name “The collapsible book cradle”.

Since creating one from a web blog by Elissa Campbell, I have made one for a miniature book (it’s so cute!) and several to distribute to various departments. I’ve just finished one for an oversize book that was just treated in the lab for the UCL’s Classics Library.
In about 2 weeks I am going to be holding a workshop to make the cradles here at the lab. I think these are a great versatile tool easy to make and easy to store when not in use.

Incendiary Films

Incendiary Films

The Public Library of Cincinnati and Hamilton County has a wonderful collection of materials about the use of the Ohio and Mississippi rivers known as the Inland Rivers Collection. Recently a group of photographs with accompanying film negatives from this collection came to the Lab.
What for? Well, film has been made using different chemicals over the years, some of which are very unstable. The Lab’s task was to divide and house the entire grouping according to film type. Special attention was given to identifying any cellulose nitrate negatives and isolating them in separate storage housing with the recommendation they be digitized and then disposed of in accordance with Ohio’s guidelines for discarding hazardous materials.
Cellulose nitrate film was the first widely used flexible plastic film. In the late nineteenth century it supplanted heavy, fragile glass plates. Great! Except nitrate is also a chemical component in gunpowder. As cellulose nitrate film degrades it goes through several distinct stages, beginning with silver mirroring and yellowing. Then it may become sticky and smelly (nitric acid odor). Gradually the negative changes to an amber color with the image beginning to fade. Eventually the negative can soften to a point where it may stick to adjacent pictures or its enclosure. In the final stage it turns to a brown acidic powder. As deterioration progresses it accelerates and in the last stages the film may begin to generate its own heat and ignite. A cellulose nitrate fire doesn’t need oxygen to burn so most of the usual firefighting methods won’t put it out. Any grouping of cellulose nitrate film increases the risk. Reels of motion picture film contained in metal canisters concentrate the off-gassing and accelerate the deterioration process.
