Judging a Medieval Book by its Cover

What a clever device the book is. It is compact and light, yet contains hundreds of pages that hold an incredible amount of information. Moving forward or backward in the text is as easy as flipping a page, while the book’s square shape and flat bottom facilitates easy shelving. Still, the object is useless if the information it contains cannot be found. And so tools were developed to help the reader do just that, such as page numbers, running titles, and indices. As familiar as these aids may be, they are older than you think. The page number, for example, is encountered in papyrus manuscripts made some two thousand years ago (see this older blog post).
