To the despair of librarians everywhere, marginalia has marched on

Were you one of those students who, despite your teachers’ warnings, continued to write in your books? If so, you have a lot of company—some of it illustrious (no pun intended). And now, there are a number of efforts going on around the world to capture these scribbled snippets of wisdom.

The notion of “marginalia,” or making handwritten notes and drawings in the margins of book pages, dates back as far as the Middle Ages. Presumably, monks made random drawings and notes to relieve the tedium of the manuscripts they were copying. Once mechanical printing started, marginalia really took off as scholars of the day held debates with the books they were reading—not so different from comment sections on websites.
