The Book Cover Archive is a compendium of the best of cover design, organized in some really useful ways. It’s the work of designers Ben Pierratt and Eric Jacobsen, and they’ve clearly put a lot of thought into the project. Not only can you search by authors, illustrators, and publishers, but also by designers, who are often the unsung heroes of a book’s success. (Don’t let anyone ever tell you people don’t judge a book by it’s cover.)
