Inklings
"Properly speaking," wrote Warren Lewis, "the Inklings was neither a club nor a literary society, though it partook of the nature of both. There were no rules, officers, agendas, or formal elections." As was typical for university literary groups in their time and place, the Inklings were all male. 
Readings and discussions of the members' unfinished works were the principal purposes of meetings. Tolkien's "The Lord of the Rings", Lewis's "Out of the Silent Planet", and Williams's "All Hallows' Eve" were among the novels first read to the Inklings. Tolkien's fictional Notion Club (see "Sauron Defeated") was based on the Inklings. Meetings were not all serious; the Inklings amused themselves by having competitions to see who could read the notoriously bad prose of Amanda McKittrick Ros for the longest without laughing.
Tolkien fandom
Across the continent, Glen GoodKnight founded the Mythopoeic Society in California in 1967 for the study, discussion, and enjoyment of fantastic and mythic literature, especially the works of Tolkien and fellow-Inklings C. S. Lewis, and Charles Williams. The society held its first Mythcon conference in 1970, which featured readings, a costume competition, an art show, and other events typical of science fiction conventions of the day. The society's three current periodicals are "Mythprint", a monthly bulletin; "Mythlore", originally a fanzine and now a peer-reviewed journal that publishes scholarly articles on mythic and fantastic literature; and "The Mythic Circle", a literary annual of original poetry and short stories (which replaced the Society's earlier publications "Mythril" and "Mythellany").
