This is post 1,454 for this blog.
There’s general agreement that the first copies of the Gutenberg Bible were finished in 1454 or 1455.
Last time, I had finished resewing the book using a ‘conservation chainstitch’. Historically, the book would have been sewn onto cords, but given the way I had to re-join all the pages into sections, I decided to use a sewing structure which is more gentle on the folios. When the time comes to make the leather cover, I’ll position fake cords (the ‘bands’ you see on old leather-bound books).
With the sewing done, first I applied a light coat of adhesive to the spine and then a strip of thin handmade paper. I ‘shaped’ the spine a bit to have a slight curve and allowed it to dry overnight. The next day I put the book into a ‘finishing press’, with the spine sticking up:
See how the sides of the press drop away from the book? This allows you to use a ‘backing hammer’ to lightly shape the spine more completely with slight glancing blows, molding the curved shape more completely. This is done to help accommodate the thickness of the sewing thread in each section, and gives the book that very characteristic rounded-spine shape we’re used to on leather-bound books.
Next, I made some endbands (head & tail bands), using a bit of maroon goatskin shaped over a heavy cord. Sewing on nice head & tail bands would most likely been done historically, but it is a bit time-consuming, and again puts stress on the folios of the book. This sort of added-on endband is common now, and they’re just applied with adhesive so they can be easily removed without damage to the folios if/when the book needs conservation treatment in the future.
The endbands serve a couple of different purposes. One, they provide support for the part of the leather cover which spans the spine from front to rear board. This helps to stop that portion of the leather cover from either being mushed down or stressed too much from people using it to pull a book off a shelf. But it also gives a nice ‘finish’ to the sections, in case there were any slight irregularities in positioning during the sewing.
Once the endbands are positioned, I apply a section of light, fairly open-weave cloth which will function as a hinge to help mount the text block to the covers. Then another strip of slightly thicker paper goes on the whole spine, from endband to endband, making a sandwich which will help support everything.
And poof – the book is now ready for a cover.
