High Quality Content by WIKIPEDIA articles! The Internet Speculative Fiction Database (ISFDB) is a database of bibliographic information on science fiction and related genres such as fantasy fiction and horror fiction. The ISFDB is a volunteer effort, with both the database and wiki being open for editing and user contributions. The ISFDB database and code are available under Creative Commons licensing and there is support within both Wikipedia and ISFDB for interlinking. The data is reused by other organizations, such as Freebase, under the creative commons license. While the ISFDB is primarily a bibliographic research database it also contains biographic data for books, authors, series, and publishers that do not meet Wikipedia`s notability standards.
