Early last year, I began working on digitization prep for what we at the Preservation Department refer to as the Hebraica Collection. Since I examine every book and look through many of them page by page, I’ve gotten to know the collection well and seen some interesting things.  Surprises found inside the books have included two tiny keys, a long dead cockroach and lots of doodles and scribbles. Below are some examples of my favorite marginalia. The first image is of a book from 1766.
