ReganBooks was an imprint of HarperCollins founded in 1994 by Judith Regan, known for high-profile, often controversial commercial and celebrity titles, including Howard Stern's Private Parts and Miss America. The imprint was renamed Regan in 2006 and shut down in December 2006 after the cancellation of O.J. Simpson's If I Did It. Regan subsequently founded Regan Arts as an independent imprint in 2014.
