What are (what is?) fan studies, you ask?
To get some idea of what fan studies is about, and what is possible in the field, check out the recently-launched online academic journal, Transformative Works and Cultures, or TWC.
TWC is an international peer-reviewed journal published by the non-profit Organization for Transformative Works. It publishes articles about “transformative works,” meaning, broadly, cultural works transformed by the individual fans and fan collectives who use and discuss them. Fan fiction, or fanfic, for example.
You can find out more by skimming the Table of Contents of their first five issues, which cover a huge range of stuff. For example, the first issue covers everything from Star Trek to Warhammer 40,000 to Hillary Clinton’s presidential primary campaign to horror fiction to BDSM “slash” fiction to theories and practices of collective (not individual) authorship.
Not a bad site to bookmark. :)
