The Mythopoeic Awards are given for works of fiction and nonfiction that exemplify "the spirit of the Inklings"--i.e. the works of J.R.R. Tolkien, C.S. Lewis, and Charles Williams.

Eligibility period	Fantasy awards (for fiction) honor books published in the previous year, including reissues, such as paperbacks, where earlier editions were not finalists. The period of eligibility for Scholarship Awards (for nonfiction) is three years, including finalists (but not winners) from previous years.
