- This introduction includes a complete chronology as set down by H. P. Lovecraft in the story The Evil Clergyman.
- The introduction is signed "—August Derleth / Sauk City, Wisconsin / 1 March 1965." It was published by Arkham House at a later date in 1965 but this title record is dated 1965-03-01 to establish a better time frame for the work other than "some time during 1965."
