So how do you find symbols in signature marks?

Co-written by Sarah Werner and Erin Blake Sarah: In my last post, I showed some examples of books that use symbols in signature marks. But how did I find these books and how might you find more examples? It’s one thing to search for books printed in the year 1542, since “publication year” is a standard search box and “1542” is written in standard typography. But you can’t really type “¶” into a search box and get useful results. (Okay, you might be able to type “¶” into your search box but you’ll get something like what Hamnet spits out: “The system could not interpret your search statement.”) I got started on this path I saw this tweet from the digitization folks at University of Oklahoma: 

The symbols of signature marks

I’ve written before about what sort of information we can learn from studying signature marks, and Goran wrote recently about the use of Latin abbreviations to indicate the gathering. So I thought the time has come to look at some of the other types of marks we find in signature marks. What comes before A? This 1579 translation of Jean Calvin’s Quatre sermons avec exposition du Pseaume 87 (STC 4439) begins with a dedicatory epistle from the translator John Field and a letter to the reader from Calvin. The sermons themselves follow, beginning on A1r and continuing through H3v. But if the main text starts with A, how are the preliminaries signed? With symbols, obviously!

Deciphering signature marks

So, as those of you who have spent any time working with early modern printed books probably recognized, this month’s crocodile mystery focuses on signature marks. Below is the photo I posted last week, now with the signature mark circled in red: Signature marks are those letters, numbers, and sometimes symbols at the bottom of the first portion of gatherings to help binders assemble the sheets of a book into the right order. For those of you who’ve been reading along with our various earlier posts on impositions, you’ll remember that books in the handpress era were printed not as single leaves, but as sheets with varying numbers of pages per side. (It’s certainly much less labor- and material-intensive than printing one page at a time.) What this means is that one sheet of paper might contain, once properly folded, 2 leaves (a folio), 4 leaves (a quarto), 8 leaves…
