Notes

Edited by Robert A. W. Lowndes
Robert A. W. Lowndes wrote a lengthy introduction to “Valley of the Lost” explaining the source of the story.

“Vol. 3, No. 1, Summer 1966 (whole number 13)” from indicia.
Each story is preceded by a short introduction, presumably by Robert A. W. Lowndes.
Review for The Dark Brotherhood gives credit for authors as “H.P. Lovecraft & divers hands.”
Pp. 129-130 consist of a “Reader’s Preference Page”, allowing readers to order this issue’s stories from best to worst.
