This book covers more than just the obvious comic book heroes like Superman, Captain America, Batman and Captain Marvel. It also includes the biblical hero Samson and the western hero the Lone Ranger and listings of obscure and one-shot heroes like Hell-Rider and the Copperhead. Because of its early 80s publication date, the book doesn't cover the more modern heroes, like those found in Image or Valiant comics. But as a whole it may still be the most useful resource on superheroes thereabouts. Information includes costume descriptions, first appearances, short biographies and an extremely interesting "comments" section. Very useful for tracking down info on old Golden Age characters that are now long gone. A very useful and excellent reference tool.
