A fanzine edited by Harry Warner, Jr. for 64 years (from 1939 to 2003).

Horizons began as a general fanzine in October, 1939 and produced on the DDT&T mimeo while Warner was also publishing Spaceways, but starting in mid-1940, after five issues, it became a fapazine and continued almost uninterrupted until Warner's death in 2003.

According to Robert Lichtman, in Trap Door #22: "He missed only one mailing in 1943 due to serious illness and another in the ‘90s because the parcel containing the issue went astray. There was a total of 252 issues, the final one appearing in this year’s February mailing. It’s safe to say that no one is likely to top Harry’s 64-year record of regular publication of the same title."

The very first work towards All Our Yesterdays appeared in Horizons.
