The story
Founded by Harry Shorten in 1957.1
Harry Shorten founded Leisure Books in 1957.
Leisure's Westerns line notably featured re-issues of the work of Max Brand, among others. The company published six titles in Nelson DeMille (as Jack Cannon)'s Joe Ryker Series in 1975–1976.
Leisure Books published the Wildlife Treasury educational animal encyclopedia for young children between 1975 and 1981.
Beginning in 1976, Leisure Books published Gardner Fox's fantasy series featuring the barbarian Kyrik: Warlock Warrior, Kyrik Fights the Demon World, Kyrik and the Wizard's Sword, and Kyrik and the Lost Queen.
By the year 2000, Leisure Books was the only American publisher with a line of horror books.
Effective September 2010, Leisure Books, along with the remainder of Dorchester's mass market paperback lines, were canceled as print publications. Future titles were slated to be available only as e-books. After pushback from authors over cancelled and unfulfilled contracts, Leisure suspended operations entirely; the parent company Dorchester shortly went out of business.
