The title pretty much says it all - unless you have a very large Ellison collection, you will probably want this just to make sure you have his most important works. A mixture of SF, fiction, essays, introductions. Edited by Terry Dowling with Richard Delap & Gil Lamont. There's at least a half-dozen award winners here, and probably more award-nominees.
