Here's a great concept for a trade paperback.At some point, most readers of the old-time Justice League probably ran across issue 51, "Z--as in Zatanna--and Zero Hour," in which Hawkman, Batman, the Atom, Green Lantern, and non-JLA-member Elongated Man help the beautiful magician Zatanna save her father.But how many people had also read the back stories leading up to that issue--Hawkman 4, Detective Comics 336, Atom 19, Green Lantern 42, and Detective Comics 355, all written by Gardner Fox--in which those heroes had originally encountered Zatanna at earlier stages of her quest?Now they're all conveniently compiled, and even if all the issues aren't as entertaining as the GL and JLA installments, the volume cares enough to add a two-page introduction and a short bonus story about the origins of Zatara and Zatanna that originally appeared in a 1980 Blue Ribbon Digest.--David Horiuchi
