As a poet, Schweitzer is probably best known for rhyming "Cthulhu" in a limerick. Despite this, he has won the 2006 Asimov's Reader's Poll for "Remembering the Future," included in Ghosts of Past and Future (Wildside, 2009); his earlier volume of serious poetry is Groping Toward the Light (Wildside, 2000). His somewhat frivolous chapbooks from Zadok Allen are Non Compost Mentis (1995), Poetica Dementia (1997), Stop Me Before I Do It Again! (1999), They Never Found the Head: Poems of Sentiment and Reflection (2001), The Innsmouth Tabernacle Choir Hymnal (2004), and The Arkham Alphabet Book: Being a Compilation of Life's Lessons in Rhyme for Squamous Spawn (2006). His nonfiction books are Lovecraft in the Cinema (T-K Graphics, 1975), The Dream Quest of H.P. Lovecrfaft (Borgo, 1978), Conan's World and Robert E. Howard (Borgo, 1978), Pathways to Elfland: The Writings of Lord Dunsany (Scarecrow, 1989), and two books of essays, Windows of the Imagination (Wildside, 1998) and Mythopoeic finalist The Fantastic Horizon: Essays and Reviews (Wildside, 2009). With George Scithers and John M. Ford he co-authored On Writing Science Fiction (The Editors Strike Back!) (Owlswick, 1981). He has edited the non-fiction anthologies or critical symposia Discovering H.P. Lovecraft (as Essays Lovecraftian, T-K Graphics, 1976/ Wildside); for Borgo, Exploring Fantasy Worlds (1985), Discovering Stephen King (1985), Discovering Modern Horror Fiction I and II (1985 and 1988), Discovering Classic Horror (1992), and Discovering Classic Fantasy (1996); and for Wildside, The Thomas Ligotti Reader (2003), The Neil Gaiman Reader (2006), and The Robert E. Howard Reader (2010).

Schweitzer was an assistant editor at Asimov's (1977—1982) and Amazing (1982—86) and co-editor (and occasionally sole editor) of Weird Tales (1988—2007); he and George Scithers were 1991 World Fantasy winners (Special Award—Professional) for the latter. With Scithers, he edited two anthologies for Avon, Tales from the Spaceport Bar (1987) and Another Round at the Spaceport Bar (1989). He edited The Secret History of Vampires (DAW, 2007) and Cthulhu's Reign (DAW, 2010), with Martin H. Greenberg, Full Moon City (Gallery, 2010), and That Is Not Dead (PS Publishing, forthcoming). Weird Trails: The Magazine of Supernatural Cowboy Stories, April 1933 (Wildside, 2004) was actually an original anthology disguised as a pulp magazine facsimile. He has also edited two volumes of rare material by Lord Dunsany, The Ghosts of the Heaviside Layer (Owlswick, 1980) and The Ginger Cat and Other Lost Plays (Wildside, 2004).

His SF Voices (T-K Graphics, 1976) was, he later determined, only the second book of author interviews published in SF. (It was preceded by Paul Walker's Speaking of Science Fiction in 1975.) His other interview books are: SF Voices 1 and 5 (Borgo, 1979 and 1980), Speaking of Horror (Borgo, 1994), and Speaking of the Fantastic [I], II, and III (Wildside, 2002, 2004, and 2011). These days he has an interview in every issue of Orson Scott Card's Intergalactic Medicine Show.

He lives in Philadelphia with his wife, the author and singer Mattie Brahen, and with the requisite number of literary cats.
