This new collection of Zelazny stories, selected by Robert Silverberg, is a good one. It contains 3 of his stronger stories from earlier collections made by Zelazny himself: "For A Breath I Tarry," "The Last Defender of Camelot," and "24 Views of Mt. Fuji."
The book also contains several other worthy stories to create a collection that spans Zelazny's career. I suspect length issues caused the selection to be limited to only 11 stories. Still, as a long-time reader of Zelazny's work since the '60s, I think he would have been better represented if I Books could have made the collection bigger. New readers of Zelazny can't easily get a feeling for the magnitude of his accomplishments with such a small selection.
The absence of "He Who Shapes" and "Damnation Alley," for instance, is to be regretted. Still, the collection is good overall. New readers who wish to read more of Zelazny's work will simply need to scour 2nd hand bookstores.
Another, somewhat irksome problem is that the collection name, _The Last Defender of Camelot_, matches that of a collection that Zelazny published himself back in 1980. That collection was probably one of his 2 or 3 best, and it was also quite large. Giving this collection the same name seems an ill-considered choice, and it will result in some confusion that should have been avoided. Most regrettable, but oh, well. At least these stories are available again, and that is a plus.
Addendum 2011: The NESFA editions of the complete stories of Zelazny now satisfy the needs of people who want to read everything in the order that it was written in. Collections like this one are still useful for introducing readers to Zelazny's work.
