TYPED LETTER SIGNED (TLS). 2 pages, with 6-line handwritten postscript, dated January 1979, to "Kirby" [McCauley], signed "Spider." On plain letter-size paper. An expletive-splattered parade of complaints from this science-fiction author, an American who moved to Canada in 1973 and "a legitimate heir to Robert A. Heinlein" (Clute and Nicholls, ENCYCLOPEDIA OF SCIENCE FICTION, p. 1016). He complains about low rates of pay at magazines, slow royalty payments from publishers, Canadian taxes, the inability of his publisher to see that STARDANCE is "a f**king perfect crossover book" and should be marketed as such, an inaccuracy in a reference to one of his stories in a letter from a Canadian anthologist, and copyeditors ("I'm pissed off at Dutton - some sonofabitch copy editor 'corrected' my grammar to conform to Strunk & White on some f**king thing."). The main news of the letter is Robinson is at work on a new novel, "a free-fall hospital," based on an "idea" supplied by "Ben" [Bova]. Kirby McCauley was probably the most important literary agent of horror, fantasy and sf writers in the boom years of the 1970s and 1980s. Good content. Faint creases where folded for mailing, several light wrinkles to margins, near fine. (#102687).
