Last month I posted a picture of a tape-laden item from the NC Mutual Life Insurance Company Archives. Progress on this collection is slow and steady, but I thought it would be fun to share a during treatment photo of tape removal and stain reduction.
Pressure sensitive tape had been applied over this horizontal tear. Above the tear, the tape carrier has been removed. The paper below the tear has been treated with solvent and washed to remove the remaining adhesive and staining. Treatment has greatly improved the text legibility and will prevent further darkening of the paper support. Next, thin Japanese paper mends will be applied to rejoin the pieces.
This week I’m working on a small collection of newsprint and other printed publications from the NC Mutual Life Insurance Company Archives. This set of materials has been closed to patrons due to some pretty obvious condition issues that make handling risky, but represent some of the few remaining copies of publications from this important organization. This issue of The North Carolina Mutual from August 1903 is, by far, the worst in regard to the amount of pressure sensitive tape that has been applied. I’ve spent the last couple of days just removing tape carriers and reducing adhesive. So far I’ve encountered five (!!) different kinds of tape, all layered on top of one another, in what I’ve started calling a “tape lasagna”. In some places, the original paper support is gone – there is only a hardened bundle of tape.
I’m assuming this item once lived in a 3-ring binder and over time became more and more damaged at the vertical fold and horizontally across the sheet as the pages were turned. I can imagine that over the last 100 years many different custodians took it upon themselves to repair this document and just reached for whatever tapes they had nearby. The earliest (i.e. lowest) tape layer has a glassine carrier, which has darkened a little. Fabric tape was then applied over this to reinforce the binder holes punched along the spine fold. The third layer is tape with a cellophane carrier, which has oxidized and turned dark yellow. Here and there I have found what appears to be a polyvinylchloride film tape and, finally, some more modern cellulose acetate tape at the very top of the heap. I have had to employ a number of different techniques to release each kind of tape, including heated tools, poultices, and solvent chambers. Removing those repairs will take a considerable chunk of time, and some yellow staining still remain. For now, at least, this project feels like a combination of an archaeological dig of office supplies and a jigsaw puzzle.
Regular readers of this blog may remember when I shared some photos of a fun little copy of the Dance of Death a few weeks ago. The front board had come off, so it was looking a little sad.
It felt a little strange to leave the treatment story of this item unresolved, though. Here are a few more images of the book after treatment.
After firmly re-attaching the front board, I covered the split leather along that joint with a thin, flexible overlay of toned Japanese paper. The leather had been very heavily dressed at some point, and that coating had become quite dark over time. I was able to remove the coating during treatment, which brightened up some of the tooling on the boards and spine.
This little Dance of Death is now ready to head back to its home in the stacks… or to the reading room to remind researchers of their own mortality.
Today is Good Friday and we happen to have our three-volume octavo edition of Audubon‘s Quadrupeds of North America in the lab to get some stabilizing repairs and enclosures. The first volume of the set is absolutely teeming with prints of hares and rabbits and this seems like an auspicious day to share them. Audubon’s Quadrupeds first appeared in three folio volumes (under the title “The Vivaparous Quadrupeds of North America”) between 1845 and 1848. The first octavo edition was published by John James Audubon’s sons (John W. and Victor) following his death in 1851. Initially both editions were issued in parts. You can view full a full digitized version of this book here.
Today was a busy day in the lab. We had 25 people come through on three tours, and we had to help set up for a tour in another department. Today is also the due-date for our performance evaluations. When life gives you a Friday like that, finding a beautiful illustration of cephalopods is a gift. I especially like the center illustration of the eyeballs.
This is one book in a serial on biodiversity. It is French, dated 1889, and beautifully illustrated. Some volumes in this series are available in Hathi Trust. I also found the page on mollusks, which was equally beautiful. This one is getting a custom box to keep it safe.
The other day a pretty somber, but intriguing little book came into the lab.
Just from the decoration, the subject is pretty apparent.
It turns out this is the first authorized edition in Italian of the Dance of Death, printed in 1549 (the binding is from a later period). The book is just one example of a long-standing artistic genre which seeks to remind the reader or viewer that no matter one’s station in life, death comes to us all. The wonderfully detailed woodcuts, designed by Hans Holbein the Younger, depict a personified Death interacting with kings, the clergy, and commoners alike.
This particular volume is interesting because it has been extra-illustrated. Probably at the time it was put in it’s current binding, leaves of thicker wove paper were added to the textblock and engraved copies of the woodcuts were tipped to them. While the designs are sometimes mirrored, it is interesting how faithful the engravings are to Holbein’s original composition.
If you would like to see more of the images, you can view a digitized copy of this book online here. This item will get a few straightforward stabilizing repairs so that it is safe to handle in the reading room. This seems like a good candidate for Rubenstein’s annual Screamfest event in the Fall.
Readers who celebrated Chinese New Year just a few weeks ago will know that 2017 is the Year of the Rooster. Fittingly, this wonderful painted scrapbook from the Charles Bailey Reed Collection recently came into the lab. Reed served as a radiologist in the U.S. Medical Reserve Corps in France during World War I. This scrapbook contains postcards, newspaper articles, photographs, and other ephemera from various cities in France, dated between 1914 and 1924. I just really love the image of the rooster crowing atop a discarded Pickelhaube, signalling the return to regular life after the war.
Last month, Senior Conservator Erin Hammeke shared her treatment of a caoutchouc binding, which incorporated a clamshell enclosure with integrated cradle. There are many items in the collection that can benefit from an enclosure like this (henceforth referred to simply as a “cradle box”): books which require a restricted opening to reduce the risk of further damage, collection material that is used frequently, or items that are exhibited at library events outside the reading room. Our History of Medicine Collection has several items which meet these criteria and everyone in the lab was interested in learning how to make a cradle box. This week we dedicated a boxing day to this project, which served both as a training exercise and supports use of the collection.
While several variations on structure are described in publicly available resources (see the AIC Wiki), we decided to all just stick with Jeff Peachey’s design. The benefits to this design are that the cradle fits the book very well and is attached to the box, so you don’t have to worry about it being removed and getting lost. We could also rely on Erin’s previous experience and help each other through the more complicated steps!
Construction begins by measuring the book at the intended opening angles to determine the sizes of the individual parts of the cradle. As with measuring for exhibit cradles, it’s much easier to prop the boards up with cushioned weights before taking measurements.
Then those pieces are cut from Davey board…
… and covered in book cloth. The cradle is essentially constructed in two pieces, which are attached by a cloth spine piece. The image below shows the interior of one cradle side during covering (left), including the adhered ends of cloth tape that allow the user to lift up the cradle (right).
Once the cradle is complete, the book is placed inside and the entire sandwich is measured for the clamshell box. The box is constructed in the usual way, but the right side of the cradle is attached to the interior of the smaller tray near the spine.
It was a lot of fun to approach learning this enclosure design as a group. If one of us hit a roadblock or did not quite understand the next step in the instructions, we could all talk it through together. Over the course of the day, we developed new techniques for completing steps or learned from each other’s mistakes. And, more importantly, now six more books from the collection will have cradles with them wherever they go!
While we are always trying to maintain an awareness of new techniques and materials for conservation through the literature, sometimes it can take a while to experiment and actually put them to use. Recently, I have finally gotten around to trying my hand at making and applying cast acrylic films for book repair; a technique which I had originally seen presented by Grace Owen-Weiss and Sarah Reidell at the Library Collections Conservation Discussion Group of AIC back in 2010 (See the Book and Paper Group Annual Vol 29, p. 92). Using a silicone mold, a blend of acrylic gels, and a paper or textile support, one can employ this technique to create a thin, reversible repair material that matches both the color and texture of the object.
This bound serial came into the lab several months ago, exhibiting some splitting of the leather at the joints and corners. Luckily the boards were still firmly attached, so it just needed some minor, stabilizing repairs to reduce the potential for further damage or loss. There is a lot of variation in the color of the red leather, either from light damage (evident on the marbled paper on the back board), pollution, or handling, which gave me the opportunity to make several different samples of film to match the various colors.
Bookbinding leathers come in such a variety of grains and surface textures, so I started by making a silicone mold with two different grains. The brown leather on the left is a piece of goatskin from Harmatan, while the black piece on the right is actually fake leather from an old backpack. These were adhered to a piece of davey board, placed in the bottom of a bristol board tray, and then the 2-part mold material was poured over the top.
Interestingly enough, the fake leather grain was a better match for this book. After applying the acrylic mixture to the mold, a thin Japanese paper support is applied on top. After drying, the film can be peeled away from the mold. Sarah Reidell has a really wonderful bibliography on her website, where you can find step-by-step instructions for creating the acrylic films, so I won’t go into more detail here.
This technique produces a repair material that is quick and easy to apply, but visually blends much better than a toned Japanese paper repair. There are so many opportunities for experimentation using this technique, with the support materials, the application methods of the acrylics, and textures of the molds. I’m very excited to add this to our stable of techniques that we can employ here in the lab.
