Tor Books is the primary imprint of Tor Publishing Group (previously Tom Doherty Associates), a publishing company based in New York City. It primarily publishes science fiction and fantasy titles, and is the largest publisher of Chinese science fiction novels in North America. History Tor was founded by Tom Doherty, Harriet McDougal, and Jim Baen in 1980 (Baen would found his own imprint three years later). They were soon joined by Barbara Doherty and Katherine Pendill, who then composed the original startup team. Tor is a word meaning a rocky pinnacle, as depicted in Tor's logo. Tor Books was sold to St. Martin's Press in 1987. Along with St. Martin's Press; Henry Holt; and Farrar, Straus and Giroux, it became part of the Holtzbrinck group, now part of Macmillan in the US. In June 2019, Tor and other Macmillan imprints moved from the Flatiron Building, to larger offices in the Equitable Building. Imprints Tor is the primary imprint of Tor Publishing Group.
