A waste of paper, glue, ink, and money. Paging through, this seemed to be an encyclopedic approach to comic book villains, but the author made finding the information as difficult as possible. The organization, which divides male and female culprits, aliens, monsters, and such, is useless. Simple alphabetizing would make the book easier to use. Most entries are surprisingly uninformative. Because so many (most?) antagonists appear in comics multiple times, a bibliographical list with each entry would have been invaluable to researchers. Facts and appearances are left out, making the missing bibliographical listings even more necessary. These things alone make the book virtually useless for researchers. The prose is occasionally obscure, the illustrative choices inexplicable, and most of the spotlights and features (longer looks at villains or villain types) promise less than they deliver. There is an excellent reference book to be written on this subject. This is not it.
