Don Markstein's Toonopedia (subtitled A Vast Repository of Toonological Knowledge) is an online encyclopedia of print cartoons, comic strips and animation, initiated February 13, 2001.

Donald D. Markstein, the sole writer and editor of Toonopedia,[1] termed it "the world's first hypertext encyclopedia of toons" and stated, "The basic idea is to cover the entire spectrum of American cartoonery."

During 2001, he settled on his final title, noting, "Decided (after thinking about it for several weeks) to change the name of the site to Don Markstein's Toonopedia, rather than Cartoonopedia.

However, if you're working on a story that deals with pop culture, that focuses on a particular time period, or that touches on classic villains and superheroes, Don just might become your own personal hero.
