The entirely self-explantory Book Cover Archive launched this week, thanks to collaborators Ben Pieratt and Eric Jacobsen.

Search for books by title, author, designer, art director, photographer, illustrator, genre, publication date, or publisher to find the tome you're interested in. The archive is nowhere near exhaustive - yet - but it does seem headed in that direction.

Plus, remarkably, they promise to one day deliver "type identification". That should save you a flurry of emails to your dearest type expert when you see something you like.
