In 1972 and 73, Gerrold published nine books: two non-fiction books about
Jornada nas Estrelas (1966), an anthology, a short story collection, and five novels. The novels were Yesterday's Children (the first Star Wolf novel), When Harlie Was One (1972 Hugo and Nebula award nominee), The Man Who Folded Himself (1973 Hugo and Nebula award nominee), Space Skimmer (one of his most reprinted novels), and the novelization of _Battle For The Planet Of The Apes (1973)_. (Gerrold can be seen as a dead ape in one of the movie's climactic scenes.)
