Paperback Library began publishing in 1961 in New York. They covered all genres, using authors such as Harlan Ellison and artists like Robert McGinnis. In 1970, they were purchased by Warner Brothers and would soon be renamed Warner Books.
The Time Warner Book Group, including Warner Books (formerly Paperback Library), was purchased by Hatchette Livre in 2006 creating Hatchette Book Group USA. The Warner line continues to exist under the Hachette Book Group USA as Grand Central Publishing.
