The Encyclopedia of Fantasy is described as the first comprehensive encyclopedia of the fantasy field, covering more than 4,000 entries and over 1 million words. It covers fantasy in literature, film, television, opera, art, and comics, with analysis ranging from early precursors such as Shakespeare and Dante through to Tolkien, C. S. Lewis, Ursula K. Le Guin, Peter S. Beagle, Stephen R. Donaldson, and Jostein Gaarder.
The Encyclopedia of Science Fiction is presented as a major expanded reference work, much more than a simple update of the earlier edition. It includes more than 4,300 entries and around 1.2 million words, reflecting changes in science fiction across game worlds, shared worlds, graphic novels, film and TV spin-offs, technothrillers, SF horror, and related imaginative fiction.
