Otherkin History

Orion Scribner wrote the awesome Otherkin Timeline: The Recent History of Elfin, Fae, and Animal People. For anyone who thinks the phenomena of otherkin was invented on tumblr or LiveJournal or even on the Internet at all, this document will be very enlightening, although unfortunately they stopped working on it in 2012 and it only covers up through 2011. "Spanning from approximately 1972 to 2011 inclusive [...] Events covered include the coining of jargon, the publication of books, the rise and fall of various parts of the community, the development of philosophical explanations for being otherkin, and much more." (You can see more of Orion's documentary writings, like an otherkin jargon lexicon and a bibliography, on their website.)

A thread from the Usenet newsgroup alt.vampyres in 1996 regarding connections between fae and vampires. Alt.vampyres was one of the places "otherkin" conversation used to congregate before we had all the mailing lists, message boards and other stuff devoted specifically to the topic.

The Elf Queen's Daughters and the Silver Elves - spans 1973 to 2011, on the history of the Magical Elven Love Letters and articles and correspondence published in Green Egg Magazine, as well as latter-day activities and writings of the Silver Elves. (The folks who made up the Elf Queen's Daughters have laid down the elven banner and gone on to more general magical pursuits.)
