Upcoming Workshop: The Conservation of Leather Bookbindings

In this variant of sewing support extensions that I came up with,  new thread is carefully looped in signatures and under or through existing cords, without having to lift the leather on the spine.  Unlike joint tacketing, this method does not restrict the movement of the book spine at the shoulder.

 

I’ll be teaching this week long workshop for at Notre Dame University, South Bend, Indiana, March 9-13, 2020. The workshop will be devoted to a wide variety of contemporary book conservation techniques to deal detached boards, arguably the most common place books fail. There was much lively and informative discussion when I taught this two years ago at Emory University, and plenty of demonstrations and hands-on work time. The workshop details forty-six methods — although many are combined in practice — organized into five basic groups.

This workshop is offered through the American Institute of Conservation. More info and registration here.

In this week-long intensive workshop, students will be introduced to a wide variety of current techniques used to conserve leather bookbindings. Book conservators, technicians, and bookbinders who wish to learn, expand, refresh their treatment skills are all welcome. Previous bookbinding or conservation experience is required.

Detached boards are the most common place leather bookbindings fail, and all five of the primary methods of treating this will be taught: mechanical sewing extensions and tacketing, inner hinge repairs, outer hinge repairs, interior-board repairs (both splitting and slotting), and several styles of rebacking. Many treatments involve a combination of these techniques. Questions concerning methods of consolidating older leather, the archival qualities of modern leather, and leather dyes will be discussed. A variety of methods to pare, consolidate, and lift leather will be introduced. Since a sharp knife is crucial to success in leather work, sharpening and easy ways to maintain a sharp edge will also be taught.

Participants should bring six to eight non-valuable leather bound books to practice on. It would be best to have a mix of tightback and books with hollows, and avoid case bound books. Skills to be learned include leather paring with a knife and paring machine, how various tools and machines for leather paring including a modified 151 spokeshave, and how to choose an appropriate lifting knife or tool for the task at hand.

There will be individual consultations with students before the workshop to discuss potential treatments for their chosen books, and determine if extra materials or tools might be required. Decision making based on the actual books brought to the class will be foundational.

The primary goal of this workshop is to equip participants with a more nuanced understanding of the pros and cons of currently practiced leather conservation techniques, gain supervised experience while performing them, and feedback when they are completed.

A Mid-20th Century Ace Bandage

Ace Bandage in original box. Mid-20th century.

Like many bookbinders and conservators, I’ve used Ace bandages for many years. They are almost essential when rebacking leather bindings (apologies to Bill Minter) since nothing else has the gentle stretch and breathability. I never really wondered about the name, assuming the word “Ace”  meant something like excellent, marvelous, or first-rate.

So I was interested to learn, upon purchasing an older Ace bandage in the original box, that it is an acronym for “All Cotton Elastic”.

According to the blurb on the original box,”This Ace Bandage obtains elasticity from the unique weave and its properly twisted warp of long-fibered Egyptian… Washing restores elasticity.”  The familiar looking brass clips were patented by Fairleigh Dickinson in 1933, though there are only two teeth on each end, not three as drawn in the patent. The patent expired in 1950; most Ace bandages I’ve seen use something similar.

The original patent for the Ace bandage fastener.

 

A bandage I have from the 1990’s is a looser weave, and doesn’t conform as well to irregular surfaces. One from the 2010’s made by 3M has “latex free” printed on it, is less breathable, possibly containing synthetic fibers. This is a good reminder that something that we generically call an Ace bandage may have significantly different working properties.

The older bandage stretches less when tensioned than either of my newer ones, so it can apply more compression in use. Yet another item to keep an eye out for while conducting primary research at flea markets and antique malls; aka. shopping.

Upcoming Workshop: The Conservation of Leather Bookbindings

I’m excited to be teaching this one week workshop in the fall.  It is based on the types of treatments for leather bookbindings that I use most in my own book conservation business. Emory University, the site host, has a board slotting machine which participants will be able to try out. Atlanta is a hopping city, inexpensive to fly to, great food, and the weather is usually pleasant in early November.  I will also be giving a lecture on the history of book boxes Friday November 2, if you want to spend the weekend. Please join us!

The Conservation of Leather Bookbindings

Emory University Libraries, Atlanta, Georgia

November 5 – 9, 2018

Sponsored by the Southeast Regional Conservation Association.

In this week-long intensive workshop, students will be introduced to a wide variety of current techniques used to conserve leather bookbindings. Bookbinders, technicians, and conservators who wish to learn, expand, or refresh their treatment skills are all welcome. Previous bookbinding or conservation experience is required.

Detached boards are the most common place leather bookbindings fail, and all five primary methods of treating this will be taught: mechanical sewing extensions and tacketing, inner hinge repairs, interior-board repairs (both splitting and slotting), outer joint repairs, and several styles of rebacking. Many treatments involve a combination of these techniques. Questions concerning methods of consolidating older leather, the archival qualities of modern leather, and leather dyes will be discussed. A variety of methods to pare, consolidate, and lift leather will be introduced. Since a sharp knife is crucial to success in any leather work, sharpening will also be taught.

Students should bring six to eight non-valuable leather bound books to work on, though there will be additional books provided to practice with. Participants will be taught how to pare leather with a knife, use a board slotting machine, a modified 151 spokeshave, a variety of lifting knives and tools, and a double edge razor blade paring machine. There will be individual consultations with students before the workshop to discuss treatment goals for their chosen books, and determine if extra materials or tools might be required. Decision making based on the actual books will be discussed. The primary goal of this workshop is to equip participants with a more nuanced understanding of the pros and cons of currently practiced leather conservation techniques, gain supervised experience while performing them, and feedback when they are completed.

Application: Registration is limited. Participant selections will be made by the SERCA Board of Directors via the following order: SERCA members (new or renewing), practicing conservators in the Southeast, and other qualified applicants. Applications are due Friday September 14th, 2018.

Please send your resume and one paragraph stating why this workshop would be useful in your conservation career to: Kim Norman, Head of Library Conservation at Emory University (kim.norman@emory.edu)

Cost: $900 for existing SERCA members, $925 (including $25.00 SERCA annual membership fee https://sercaconservation.org/membership/) for new and renewing SERCA members. Payment taken after review of applications.
