Fresh from the fertile minds of some of today's most imaginative writers comes a collection of short fiction that takes readers behind the scenes to unmask conspirators and their plots, some of which may even be true. Original.
Various is the correct author for any book with multiple unknown authors, and is acceptable for books with multiple known authors, especially if not all are known or the list is very long (over 50).
If an editor is known, however, Various is not necessary. List the name of the editor as the primary author (with role "editor"). Contributing authors' names follow it.
Note: WorldCat is an excellent resource for finding author information and contents of anthologies.
A tepid collection of stories involving conspiracies of all sorts. While I usually enjoy Martin Greenberg's anthologies, since there's always a few gems in every collection, this book lacked any memorable tales. Most were fairly uninspired stories that either had major plot holes or were confusingly dense. Not the worst book I've ever read, but still pretty forgetable.
