Namesakes

Apparently the old Adam West Batman show had a supervillain called the Bookworm (played by Roddy McDowall), whose lair was a library, whose henchmen were named Printer's Devil, Typesetter, and Pressman, and whose power was to read books in a matter of seconds, giving him the knowledge of all recorded criminal plots.

How cool is that?

Of course, this being the 60s Batman, he merely speaks in quotations and leaves Riddler-esque literary clues to his crimes.

For a darker, more modern twist on the literary-minded supervillain, there's Tatterfiend from Madness: Minority of One, a (regrettably incomplete) Justice League fanfic.
