Horwitz ventured into paperbacks in the 1940s, under the imprint Transport Publishing Co, with series of 'Sporting Westerns' and 'Scientific Thrillers' and Australia's first science fiction magazine Thrills Incorporated (1950-2).
[9] Between the 1950s to the 1990s, Horwitz published some of the most popular pulp fiction writers, including A.G. Yates aka Carter Brown[10] and Marshall Grover, in numerous successful author and title series.
[14][15] In the late 1950s, Horwitz published some original Australian comics, notably adaptations of its Carter Brown novels,[10] but also "The Phantom Commando", created by John Dixon but mostly worked on by Maurice Bramley, who drew it until 1956.
[4] By the 1960s, Horwitz boasted a considerable number of successful authors and had built sufficient momentum to survive the lifting of import restrictions in 1958.
While generating business for local writers and artists, the firm also acquired overseas material and reprinted them with title and cover changes, often complying with Australian censorship guidelines.
"[18] Although horror pulps were not as popular as detective and romance, Australian publishers still committed themselves to pushing out 'spine-tingling' titles in that genre.
[19] More often than not the stories he used were out of copyright tales by overseas writers such as Bram Stoker, Edgar Allan Poe, Charles Dickens, Guy de Maupassant, Sheridan Le Fanu and so on.
Examples of the horror novels include "Throne of Satan", "The Witch Hunters" (1963) and Sweet taste of Venom (1963, as by Dark).
[25] Other writers in the Horwitz Gothic Library series apart from 'Farr' included Jane Gordon, Clara Coleman, Wilma Winthrop and Fiona Murray.
[27] Its magazine division produced material for the adult, sporting, entertainment, audio visual and children’s markets.
