Notes: No printed price. Price from an ad in Locus #248 (September 1981). The Author Index begins on page 647, and the Title Index begins on page 691. Neil Barron edited the book; the individual chapters are written by different contributors; the annotated bibliographies offer "compare to" suggestions for similar books. The book has a complex rating system based on recommendations of reputed authors and critics, for a "core collection" for librarians and collectors. A useful and readable genre reference.
