[2] Several of the articles originally published in Amra were later reprinted as part of two volumes about Conan the Barbarian, which Scithers co-edited with L. Sprague de Camp.
In 1963, Scithers chaired Discon I, the 21st Worldcon, held in Washington, D.C.[4] He was a regular parliamentarian for business meetings of the World Science Fiction Society and authored a guide to running science fiction conventions, The Con-Committee Chairman's Guide based on his experiences chairing DisCon 1 in 1963.
In 1988, he worked with John Gregory Betancourt and Darrell Schweitzer to re-establish Weird Tales, the magazine that had introduced one of his earliest interests, Conan the Barbarian, to the world.
He was a member of the all-male literary banqueting club the Trap Door Spiders, which served as the basis of Isaac Asimov's fictional group of mystery solvers the Black Widowers.
[citation needed] He resided in King of Prussia, Pennsylvania where Weird Tales was edited in his basement, followed by Rockville, Maryland.
