The Conservation of Leather Bookbindings Workshop Review by Kasie Janssen

One month ago, I was able to attend The Conservation of Leather Bookbindings at the University of Notre Dame. The American Institute for Conservation (AIC) and the Foundation for Advancement in Conservation (FAIC) supported this 5-day workshop that was taught by book conservator and tool-maker Jeff Peachey. Conservation is a field that requires a constant love of learning new skills and techniques, so when I saw this workshop was hosted not too far from Cincinnati, I jumped at the opportunity to increase my knowledge on the conservation of leather bookbindings.

Leather is an interesting topic in book conservation, as many of the historic books we work on have full or partial leather bindings. Leather, like paper, comes in a variety of qualities, and has inherent issues as it ages over time. And we, as conservators, have many ways to combat these issues to make the books in our collections accessible to all.

This workshop offered an in-depth look at the many ways leather can be conserved, while also discussing the pros and cons of the various types of treatment options. This level of understanding is crucial part for us.  Think of it like taking a test – you can simply have the list of answers, or you can study and understand why the answers are in fact correct (any teacher will tell you they prefer the latter of these two options, and we do too!).

Joint tacketing and sewing extensions.

While the leather on the outside of a book is what most of us see when we look at our books and bookshelves, a large portion of the workshop focused on how those books are put together. If you’ve seen a leather book, you have likely seen a book that has its covers detached or missing. We talked about reattaching covers using techniques such as joint tackets, sewing extensions, slitting and slotting the boards, and tissue repairs. These are techniques that need to be considered before a leather reback, which was the final technique we learned, would take place.

One of the most beneficial aspects of the workshop was that we were able to practice these techniques on our own books. (I’ll take this time to note that these were not collection items! We like to practice on models or personal books first.) Being able to learn about the techniques and then practice them was a great way to use the hand skills needed for these types of treatments. Having our own personal examples that were treated also provides an application of how these techniques work and wear over time.

The workshop also covered leather dying, as well as knife sharpening – a crucial tool for working with leather, and leather paring techniques and tools.

I have to say, the workshop happened in the week before Covid-19 began impacting the United States on a massive scale. All of the attendees remained in contact with their home institutions and families throughout the week as news progressed. The workshop, though, provided a sort of conservation utopia where we could turn off the news and focus on the profession that we all love. Jeff Peachey was an incredible instructor, offering vast amounts of knowledge and insight that we can apply to our day-to-day work. And the staff and facilities at the University of Notre Dame provided the perfect environment for our leather conservation deep dive. A sincere thank you to Jeff, the University of Notre Dame, AIC and FAIC for the wonderful workshop.

While I continue my work-from-home, I will be finishing a few of the treatments I had started during the workshop, and also practicing things like leather paring, leather dying, and repair techniques. This will ensure that when we are back in The Preservation Lab, I’ll be able to provide assistance on many of the damaged leather books that are waiting for our tender loving care.

The Conservation lab at Reyniers recently hosted a week-long workshop with Jeff Peachey on the Conservation of Leather Bookbindings, organized by Liz Dube and supported by the American Institute for Conservation. You may remember Jeff from his 2018 presentation in Rare Books and Special Collections on his treatment of Dante’s La Commedia, from 1477.

Seven conservators took part in the workshop, in addition to our conservation staff at Reyniers. The hands-on, intensive workshop covered treatment decision-making, various repair techniques, leather working skills, and tool sharpening. Our group took time out to visit RBSC to view the 1477 Dante up close with Jeff and enjoy the exhibits on display. Thanks to Julie Tanaka for hosting our group.

The workshop provided the rare opportunity to learn, practice, and share with colleagues from other institutions. It was a lot of fun! We are grateful to Jeff, and to our colleagues who were able to make it to campus and stay focused during such a challenging week. Special thanks to Tosha McComb, Neil Chase, and Kathy Colbert for their flexibility and support during the workshop.

Conservation of Leather Bookbindings Workshop

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.
