To preserve the history of transformative works and the fandoms from which they have arisen, the Organization for Transformative Works established Fanlore, its own fandom wiki. The beta version of Fanlore launched in September 2008, and the wiki came out of beta in December 2010. As of January 2019, more than 46,000 pages have been created on Fanlore, with more than 830,000 edits made by more than 35,000 registered users.

Fanlore provides a framework within which fans can document their understandings of and experiences in fandom, past and present. This encyclopedic resource is a living archive of fandom history for the benefit of fans themselves. It seeks to document past fandom occurrences, as well as to preserve current discussions and debates for future reference by recording history as it happens. It also gives context for outside media, academics, and people new to fandom, in a format where fans are in control of their own representation.

Fanlore content is created by fans. Any and all fans are encouraged to join the project and share ownership of the wiki’s content. Fans are encouraged to contribute by creating new articles, adding details to pages, or contributing their own point of view to articles to update, debate, or widen out the understanding of topics. Some Fanlore editors undertake specific editing projects, such as the media fanzine project, through which thousands of pages have been created. Fanlore also hosts regular editing challenges, such as the annual April Showers challenge. Gardeners watch over recent edits to make sure all contributions are properly integrated and to provide support to our fan contributors. The wiki is by its nature always a work in progress, and the Fanlore committee provides support, guidance, and encouragement where needed.

All original content is available under a Creative Commons license; anyone is welcome to make copies to host on other sites. The wiki was built with open-source software.
