Love this idea of the graphic cannon. No, not the cannon of graphic novels–these are works in the literary cannon that have been made into graphic art. Aside from being totally awesome, it sounds like The Graphic Canon: The World’s Great Literature as Comics and Visuals would be a great way for teachers to get reluctant readers interested in the classics.
Candlewick also has graphic versions of classics like Moby Dick and The Merchant of Venice, which are fantastic. Works like these might not replace the standard text version, but I think they’re an awesome accompaniment.
