About Berkley

Berkley is a New York paperback and hardback imprint founded in 1955 by Charles Byrne and Frederic Klein, two former Avon employees, and now part of the Penguin Publishing Group at Penguin Random House.

Berkley began as an independent paperback house. Its Berkley Medallion line published the American edition of J. G. Ballard's The Drowned World in 1962, following Victor Gollancz's London edition that year. G. P. Putnam's Sons bought Berkley in 1965, and when Penguin bought Putnam in 1996 Berkley came with it, joining Penguin Random House after the 2013 merger.

Its authors have included Tom Clancy, Clive Cussler, Dean Koontz, Patricia Cornwell, Frank Herbert, Robert A. Heinlein and Christine Feehan. Berkley issued the first edition of Vengeance in Death in Nora Roberts's In Death series, written as J. D. Robb, which began with Naked in Death in July 1995.

1980s to 2000s

  • Where the copyright page has a number line, the lowest figure present is the printing, so a first printing must show a "1". If a "First Edition" line sits beside the number line, go by the number line, since some publishers leave that wording in on reprints.
