The listing for this title appears this way when viewed April 28, 2004: "Superman: Adventure of Man of Steel (D C Comic Graphic Novl by Paul Scott/Dinni McCloud (Author)"
The title of the book is "Superman: Adventures of the Man of Steel "
DC Comics is the publisher.
a "graphic novel" is a description of the kind of book it is and the kind of means of communication (some would say "the language", some "the medium") it uses.
the "Authors" are Paul Dini (not "Dinni") and Scott McCloud. They were the writers of the script and dialogue of different issues collected in this book. The artists, as best as I am able to determine without having the issue in front of me (I'm not at the moment where my comics are kept) are Terry Austin, Rick Burchett & Bret Blevins. Together, artists and writers (who sometimes are one and the same) are the creator of the story, based on characters other people created and which owned owned by the corporation TimeWarner, in Superman's / DC Comic's case.
And, yes, I think Superman creators Siegel, Shuster, several of the writers and artists who came after them (whenever relevant), and the corporation all ought to be credited, for posterity's sake.
But my primary reason for writing is to get Amazon.com to hire people who know enough about what they're doing to be able to catch the more than 8 errors in this listing. Most importantly, fix the listing so that McCloud & Dini are correctly credited. They deserve the respect.
