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.
