Xero was a fanzine published by Patricia Lupoff and Richard Lupoff.
In 1960, Pat and Dick Lupoff started Xero, a mimeographed science fiction fanzine that also included general interest subjects, pop culture, and commentary on comics as well. After 10 issues it had become so successful it became too much work for the couple and they ceased publication in 1963. It won a Hugo Award for 'Best Fanzine' in 1963.
The fanzine included a review of Psycho by Harlan Ellison, a review of Kingsley Amis' study of SF, New Maps of Hell by James Blish, and Donald Westlakes's farewell to SF.
Because of its coverage of comics, Xero is considered to be the direct antecedent of later fanzines devoted to comics and featured the flip book supplement, with a series of articles on comics called "All In Color For A Dime by Richard Lupoff.
Artists contributing to Xero include Can Adkins, Cathy Bell, Larr Ivie, Eddie Jones, Roy G. Krenkel, bhob Stewart and Steve Stiles.
Comics were contributed by Landon Chesney.
Contributors included Otto Binder, James Blish, Bob Briney, Lin Carter, Norman Clarke, Avran Davison, Roger Ebert (Star*Dust), Harlan Ellison, Larry Jarris, Richard Kyle, H. P. Norton, Frederik Pohl, Bill Schelly, Roy Thomas, Don Thompson, and Donald Westlake.
