Evidently, these two groups of bookmarks—static and dynamic—provided very different approaches to marking information—and thus to a book’s use. Readers who added clip-on or “spider” bookmarks anticipated they would need to retrieve information not from one single page but from a changing number of pages. In other words, movable bookmarks served an audience with a shifting knowledge “appetite,” while the static ones encouraged a more “ritual” use of a book. In other words, both types are telling, in their own way, about medieval reading culture.

Step 3: Set up reading storage and a reading environment.

Jesuit manuals such as Jeremias Drexel’s Aurifodina, subtitled The Mine of All Arts and Sciences, or the Habit of Excerpting, explained how to best take notes from reading to create commonplace books: personal notebooks of reading extracts that contained the religious, ethical, and political maxims deemed necessary to lead a good life. There were even admonitions about which texts not to read and how not to fold page corners or to mark texts with fingernail scratches.
