Stapled Instead of Sewn

When you look at how books are generally made, you’ll find that a majority of them are either sewn with thread, glued together as individual sheets, or occasionally bound with a combination of sewing and commercial glue.

On rarer occasions, a book will be stapled together. As luck would have it, one of these books recently came across my bench in need of a new cover. At first glance, you can’t immediately tell the difference between a stapled book and a sewn book.

It’s not until you open the book up and look at the gutter of one of the signatures that you might be able to see whether the book is stapled or not.

It’s even easier once you’ve taken the cover off and can look directly at the spine of the textblock. As you can see in the images below, there are staples running through a significant portion of the signatures of this book.

Now, in a perfect world where I have all the time and patience I could want, I might remove the staples, mend any damage to the signatures in the process, sew the book back together, and then make a new cover. In this case, such an approach would be too labor intensive and time consuming. As the only senior conservation technician charged with maintaining the general collections, I cannot devote that much time to one book when I might have as many as 25 other books also waiting to be treated.

Considerations

With binding structures like this, the treatment decisions tend to boil down to preserving the provenance of the object vs choosing to rebind the book for greater longevity. In this blog post by Peter D. Verheyen in 2011, it’s evident that these wire bindings are a curious part of the history of bookbinding. Since they’re unusual, and since our goal is to conserve as much of the original item as possible, one might think that saving the original binding would be the obvious choice.

But how do technicians in general collections conservation (such as myself) reconcile keeping as much of the original object intact when we also have to prioritize making sure that the book can withstand regular use from patrons? If the staples in the binding had been so rusted that they were breaking whenever I opened the book, I would most likely take a more involved approach to the treatment of this book. An example of such a treatment would be adhering a cotton cambric to the spine and sewing through it along with the textblock, which you can see an example of in this paper by our very own Beth Doyle.

Luckily, in this case, both the paper and the staples were in good enough condition that a secondary treatment wasn’t necessary. However, it could be argued that perhaps I should have gone ahead with the more complex treatment just in case the staples failed in the future. In the end, these are the dilemmas we face in general collections conservation.

Treatment

I decided that the best course of action would be to clean the spine of its original lining and glue and replace it with a strong Japanese tissue adhered with wheat starch paste. By doing so, the spine is stabilized and strengthened while the staples are also given additional support. This reduces the potential damage that could occur from future use and repeated opening and closing of the book.

With the textblock now in a stable state, I could prepare a new case for the book. The original case had already failed and since the original materials were too fragile to keep using, it didn’t make sense to try and reuse the case. Instead, I made an inset on the front board in order to preserve the original cover material. If you’d like to learn more about the book, you can find the catalog record here.

1091 Project: Making Treatment Decisions

This month on the 1091 Project we talk about how we make treatment decisions. Treatment decisions are based on a conservator’s experience with materials, knowledge of treatment options, and understanding of the object as it relates to the collection.

Treatment Goals

Conservators must balance the item’s value to the collection, how and how much it has been or will be used, and to what extent the binding and its contents are at risk for further loss or damage. For any item in the lab we have a few overarching treatment goals:

  • Save as much of the original as possible
  • Use reversible repair methods as much as possible
  • Use high quality repair materials and adhesives
  • Repairs should not be stronger than the weakest part of the original
  • Create a sympathetic repair that does not obscure the fact that it was done (conservation vs. restoration)
  • The repair should facilitate use of the item

From there we ask:

  • Can we do it?
  • Should we do it?
  • How should we proceed?

There is an entire chapter to write just about this section, but let’s move on to the process of making a treatment decision for one book from our general (circulating) collections workflow.

Condition Review

Transactions of the Zoological Society of London, volume VI (London, 1869)

This book came to the lab because someone used packing tape to repair the damaged spine. The fragile leather binding tore off the book as a result.

The binding is a hollow-back binding in quarter leather with tight joints. The leather is weakened and failing; the marbled papers over the boards are abraded; the corners are worn; the spine and boards are off the text block; and the spine has been heavily taped with fresh packing tape, the carrier and adhesive are present, and the adhesive is very sticky.

The text block is made with wove paper and is borderline brittle and oversewn; the paste downs and flyleaf have detached; the spine adhesive and linings are intact; the sewing is intact except for the first and last few pages; the printer’s ink is stable; there are foldouts, some of them are misfolded with damaged edges; several pages at the front and back have multiple tears.


Treatment Options

Can we do it?
The two biggest problems with this book are the tape and the oversewing. If removed, the adhesive on the packing tape will take the fragile, thinly-pared leather with it resulting in a time consuming repair. Oversewing creates a very inflexible spine that restricts the opening and puts tremendous stress on the first few pages, resulting in breaks at the bound edge that are difficult to repair because of the stitching. The fastest, most economical and most practical option may be to replace the binding, but the oversewing will continue to be problematic.

The borderline brittle paper worries me. Because they are stronger than the substrate, repairs can provide a breaking edge for brittle paper. Although this paper is slightly brittle, it still has some flexibility. I think we can repair the page tears and fold-outs but it will take a lot of time.

Should we do it?
The information in this book is likely more valued than the binding by researchers. This book has only five circulations on its record. I could check with the biology librarian whether this may be a faculty favorite, it seems likely that it is.

The new binding and paper repairs will take an estimated 3-4 hours of bench time. I have one technician for the entire general collections workflow (5+ million books). Is this one book worth repairing three or four others that may have higher circulation records? Good question.

We can defer the treatment until its next use. All the parts are here, and though the boards and some pages are detached the book can be carefully used. We could make a protective enclosure (about 15 minutes of time) and put it back as-is if we think that its future use is likely not going to be high.

How should we proceed?
