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.
Of Other Worlds
Of Other Worlds is a 1966 anthology of literary criticism by C. S. Lewis and published posthumously by the executors of his estate. It was edited by Lewis' secretary and eventual literary executor Walter Hooper. The first part of the anthology consists of several essays that cover Lewis' ideas about the creation of science fiction or fantasy literature. "Unreal Estates" is the transcript of a recorded conversation between Lewis and the authors Brian Aldiss and Kingsley Amis that took place in Lewis' rooms in Magdalene College "a short while before illness forced him to retire." The second part of the book is made up of three of Lewis' science fiction stories (one of which was previously unpublished) and the beginnings of "After Ten Years", an unfinished novel set during the aftermath of the Trojan War.
