David Truesdale almost gets it right, but not quite. I started ALGOL in 1963, and in the mid-70s changed the name to STARSHIP. The mag folded in 1984. Meanwhile, in the late 1970s, I started SCIENCE FICTION CHRONICLE, which had one proto-issue appear in STARSHIP before beginning monthly publication with the October 1979 issue. SF CHRONICLE continued until I sold it to Warren Lapine's DNA Publications in 2000; he fired me in 2002, and the mag folded in 2006, a victim of the internet. Who, after all, needs a monthly news magazine when there are so many SF-oriented news websites?
The Alfred Bester story I published, "Here Come the Clones", subtitled "A Complete Short History of SF Writing With Fifty All-Purpose Footnotes", appeared first in the June 14, 1976 issue of PUBLISHER'S WEEKLY, and it was in the Spring 1977 issue of ALGOL (as it then was) on page 35-37.
However, the story, "Oh, Those Trepidatious Eyes!" by R.A. Lafferty, in the same issue on pages 38-40, was an original, never before published piece of fiction. I don't know whether it ever appeared anywhere else. And yes, I have a copyright notice from the Library of Congress on the issue...
