i’ve been reading/skimming some academic articles about fandom which you may be interested to check out—these can be found on databases like proquest if you have university or library access:
‘A Crowd at Your Back’: Fantasy Fandom and Small Press by Kim Wilkins, which is more about how fantasy small presses work, what they do, and why they’re successful, but is also about the fandom model of consumers also being creators
‘Except that Joss Whedon is God’: Fannish Attitudes to Statements of Author/ity by Judith Fathallah, which examines the fan-author relationship in terms of how much respect is afforded to authors and why, specifically focusing on support of fanfiction and how sexism plays into the way certain authors are dismissed
Emotional Landscapes of Reading: Fan Fiction in the Context of Contemporary Reading Practices by Natalia Samutina, about approaches to reading fanfic in the Russian Harry Potter fandom—i found the descriptions of a fandom dynamic different from english language fandom really interesting
and there’s so many awesome articles on the open-access Journal of Transformative Works and Cultures, such as:
The JohnLock Conspiracy, Fandom Eschatology, and Longing to Belong by Bo AllesøeChristensen and Thessa Jensen, which examines what the JohnLock Conspiracy was, why it was, and how tumblr’s functionalities shaped it
Discourse Is the New Wank: A Reflection on Linguistic Change in Fandom by Lily Winterwood, a short exploration of how and why old fandom terms became new fandom terms
