Before you take a book apart to clean and mend the pages, re-do the sewing and provide a new binding, you've got to collate it. Modern books have page numbers to keep everything in order, but back in the good old days, conventions were different; the preface, dedication, introduction might be numbered with lower case Roman numerals or not at all.
the signature is noted with an "A", the catchword corresponds to the first word on the next page |
"And" bottom left corresponds to "And" on the top right |
Plates also add another layer of complexity, sometimes they are numbered sequentially, and sometimes the printer comes up with another system. In this instance the plate is numbered according to the page it is supposed to be facing, which is a great idea, I just have to make a note as to which page the plate is actually bound with.
Books are made up of many, many moving parts that need to fit together and while page numbers and signature marks may seem like enough to re-assemble all the pieces, it is better to be safe than staring at a pile of sheets and loose plates going hmmm....
do you see the quill from someone cutting a new point? |
So, collating, in the conservation context, is a precise documentation of how each page fits into the overall sequence and structure of a book. It can seem a little painstaking to some, but I enjoy it. It is a great way to commune with a book that I am about to work on, learn something new, and notice all sorts of little details and surprises.
