The classic science & sci-fi magazine OMNI is now available on the Internet Archive. OMNI was co-founded by Kathy Keeton and Penthouse publisher Bob Guccione in 1978 and was published until 1995. The magazine featured the work of Ray Bradbury, Stephen King, William S. Burroughs, Isaac Asimov, and many others. After going out of print, OMNI lived on as one of the first webzines, from 1996 to 1998.
