The definitive Encyclopedia of Science Fiction is now online. This project started life as the 3rd Edition of the print version (previous editions published in 1979 and 1993) but rapidly grew far too large to be published: the final version of the title is anticipated to be more than 4 million words in length and contain more than 12,000 entries.

 

The current version of the Encyclopedia is the beta, consisting of about 75% of the 'final' book, which is anticipated in about a year's time. However, even the 'complete' book will still be updated on a regular basis after that time.

 

Note that this is the Encyclopedia of Science Fiction, and covers the SF genre alone. The same team produced the print Encyclopedia of Fantasy in 1996, so I assume that if this project is successfull, they will produce an online fantasy encyclopedia at a future date.

Thank you for the notification and the heads up here, Werthead. I shall definitely save that website to my browser's "Favorites."
