The Encyclopedia of Science Fiction

This from the Gollancz press release:

The third edition of the Encyclopedia of Science Fiction, the definitive reference work in the field, will be released online later this year by the newly-formed ESF, Ltd, in association with Victor Gollancz, the SF & Fantasy imprint of the Orion Publishing Group, whose support will enable the text to be available free to all users. This initial "beta" version, containing about three-quarters of the total projected content, will be unveiled in conjunction with Gollancz's celebrations of its 50th anniversary as a science fiction publisher.

The first edition of the Encyclopedia, whose founder and general editor was Peter Nicholls, appeared in 1979, and contained over 700,000 words. A second edition, edited by John Clute and Peter Nicholls, appeared in 1993 and contained over 1.3 million words. Both editions won the Hugo Award from the World Science Fiction Convention, in addition to numerous other honours. The beta version of the third edition will contain some 3 million words, including about 12,000 entries and well over 100,000 internal links. The entries cover every area of science fiction, including authors, illustrators, movies, music, games, and fanzines. The text will be completed, through monthly updates, by the end of 2012.

The third edition has been produced by editors John Clute and David Langford, Editor Emeritus Peter Nicholls, and Managing Editor Graham Sleight. Contributing Editors for the third edition include Mike Ashley on magazines, Paul Barnett on artists and illustrators, Jonathan Clements on all aspects of Japanese and Chinese SF, Nick Lowe on movies, Abigail Nussbaum on television, John Platt on comics, and Adam Roberts on music. During the Encyclopedia's development, the project has been supported by Clare Coney as Technical Editor, Roger Robinson as Research Editor, John Lifton-Zoline, and Pamela Lifton-Zoline. Robert Kirby of United Agents, The Bookseller's Literary Agent of the Year 2011, represents the Encyclopedia.

The Encyclopedia of Science Fiction will soon become available online and free of charge. Although the website is not live yet, the encyplopedia will be found here.
