SciFan is an online database for fans of science fiction and fantasy books.
The site provides detailed bibliographies, linking books together into series' where appropriate and, in turn, grouping series by universe. Books are also grouped together into themes such as "18th Century", "Alternate History" and "Mathematic Fantasy." A useful provision is access to lists of new and upcoming books, selectable by month of publication. There is also a search facility: entering a word or phrase searches within author names, book titles, series and universes.
With more than 65,000 books, 18,000 writers, and 8,000 series (as of 2008) and ongoing updates, it is one of the main databases in its field along with the Internet Speculative Fiction Database.
It was launched in 1999 by James Wallace Harris and Olivier Travers. In 2001 Harris decided to devote his time to writing, and Travers was joined by his wife Sophie Bellais as co-maintainer. They make up the maintenance team since then.
