[3][7] OTW has 1,010 volunteers, net assets of $2.5 million and at least 15,810 paying members according to its annual report in 2021.

In 2008, the OTW (in coordination with the Electronic Frontier Foundation) successfully submitted requests to the Library of Congress for further exceptions to the Digital Millennium Copyright Act to allow the fair use of video clips for certain noncommercial uses such as video remixes, commentary, and education, as well as to protect technology used for such purposes.

[13][14][15] The OTW, the Electronic Frontier Foundation, and New Media Rights submitted a new petition for exemptions in 2018.

These projects include The Fan Culture Preservation Project, a joint venture between the OTW and the Special Collections department at the University of Iowa[22] to archive and preserve fanzines and other non-digital forms of fan culture, and The GeoCities Rescue Project, which attempted to preserve content originally hosted on Yahoo's GeoCities by transferring that content to new locations on the Archive of Our Own or within the Fanlore wiki.

Time said that AO3 "serves all fandoms equally, from The A-Team to Zachary Quinto and beyond", and also called it "the most carefully curated, sanely organized, easily browsable and searchable nonprofit collection of fan fiction on the Web...".

It includes statistics from two other large fan fiction archives, FanFiction.Net (FFN) and Wattpad as well as the popular microblog platform Tumblr.

The post shows that the most active fandoms on AO3 in 2015 were (largest first) Supernatural, Dragon Age, Harry Potter, The Avengers, Teen Wolf, and Sherlock.
