Most of the work that was published in his lifetime appeared in either "Astounding" or "Wonder Stories". However, several of Weinbaum's pieces first appeared in the early fanzine "Fantasy Magazine" (successor to "Science Fiction Digest") in the 1930s, including an "Auto-Biographical Sketch" in the June 1935 issue. Despite common belief, Weinbaum was not one of the contributors to the multi-authored "Cosmos" serial in "Science Fiction Digest/Fantasy Magazine." He did contribute to the multi-author story "The Challenge From Beyond", published in the September 1935 "Fantasy Magazine". At the time of his death, Weinbaum was writing a novel, "Three Who Danced". In this novel, the Prince of Wales is unexpectedly present at a dance in an obscure American community, where he dances with three of the local girls, choosing each for a different reason. Each girl's life is changed (happily or tragically) as a result of the unexpected attention she receives. In 1993, his widow, Margaret Hawtof Kay (b. 1906 in Waco, Texas), donated his papers to the Temple University Library in Philadelphia, Pennsylvania. Included were several unpublished manuscripts, among them "Three Who Danced", as well as other unpublished stories (mostly romance stories, but there were also a few other non-fiction and fiction writings, none of them science fiction).
