Berkley Books

Berkley Books is an imprint of Penguin Group (USA) that began as an independent company in 1955. It was established by Charles Byrne and Frederic Klein, who were working for Avon and formed "Chic News Company". They renamed it Berkley Publishing Co. in 1955. They soon found a niche in science fiction works. They were bought out in 1965 by G. P. Putnam's Sons and became their paperback publisher.

In 1982, Putnam bought Grosset & Dunlap and Playboy Press, and the Ace and Playboy paperback lists were added to Berkley. The Playboy list was eventually absorbed into Berkley, while the Jove and Ace lists have continued as distinct imprints.

Following its publication of Tom Clancy's The Hunt for Red October, Berkley Books became increasingly interested in publishing military fiction and technothrillers. The publicity campaigns at military bases were part of the success Dale Brown's Flight of the Old Dog.

Today, Berkley is part of the Penguin Group USA, which purchased Putnam in 1996, and prints in mass-market paperback, trade paperback, and hardcover formats.
