Uniquely authoritative, staggeringly comprehensive and enjoyably opinionated, The Encyclopedia of Science Fiction was immediately hailed as a landmark in the genre when first published in hardback, winning the Hugo Award, the Locus Award and a BSFA Special Award.

With over 4,3000 entries and more than 1.3 million words of critical insight and biographical data — including a new appendix of updates and revisions for this paperback edition — it is an indispensable reference work not only for every reader who loves, uses and wishes to know more about science fiction, but for every reader of imaginative fiction at the end of this century.
