This is the 2008 edition of The DC Comics Encyclopedia, and it looks very comprehensive. Over 1000 characters are packed into this 400-page hardcover.
The characters are arranged alphabetically so they are pretty easy to find, and all are illustrated with beautiful images from original comic books. Since there are so many characters, the lesser known ones get only a small entry. It's a very good read with lots of interesting details on character background.
Great book for those into superheroes and comics.
