"Quinn + O'Neill I-165"
The Quinn/O'Neill edition of The Complete Stories and Poems of Edgar Allan Poe was originally published by Knopf in 1946. The copy of the Quinn/O'Neill edition in the Mabbott Poe Collection, from which the photocopy was made, is dated 1971. Thus, Mabbott himself did not use this edition and wrote neither the marginalia made in the book itself nor the marginalia on the photocopy.
