As I mentioned in a previous post, I've recently become aware of a spate of academic articles about otherkin. I managed to get my hands on the first of them, "Othering among Otherkin: The discursive negotiation of the face-threat of exclusionary othering in a demarginalizing internet community" by Melanie Getzler. I've skimmed it and it looks really great, but unfotunately I haven't had time yet to sit down and read it in depth. It's much longer than other articles on the subject, as it is a Master's thesis - 82 pages. One thing I will note is that it does not suffer from the same weakness that so many academic articles on otherkin and therians have in the past - that of being based on self-selected survey responses or interviews with a fairly small sampling of the community. Ms. Getzler employed a different methodology to try to get a truly representative sampling and while I'd still like to see a broader study done I must say hers is the best attempt to date of which I am currently aware.
For those interested, I've saved a copy of the thesis here.
Apparently Ms. Getzler also wrote an undergraduate thesis on our community entitled "Here There Be Dragons: The Effect of Online Communities of 'Otherkin' on Philosophical Construction of Self-Identity". I'm still looking for a copy of that, it is not available from ProQuest.
Another recent academic work is "Some People Aren’t People on the Inside: Online Connectivity and Otherkin Subjectivities" by Margaret Shane. I don't have a copy of that one yet either, but I do know where it can be purchased. I'm just leery of spending $30 on a 15 page paper.
Last but not least there's another article by Venetia Robertson focusing on the therian community: "The Beast Within: Anthrozoomorphic Identity and Alternative Spirituality in the Online Therianthropy Movement". This paper may be downloaded for free from academia.edu, and I have backed it up here.
