Yandro was an influential science fiction fanzine published from 1953-1986 by Buck and Juanita Coulson. Over that period, they published 259 issues, the final issue not being distributed until 1991. The headquarters was in North Manchester, Indiana. Yandro's content covered a broad spectrum of topics. It won the Hugo Award for Best Fanzine in 1965, and was a nominee for the Hugo Award 10 years in a row, from 1959 through 1968. Among other articles, Yandro featured Coulson's incisive reviews of books and, especially, fanzines.
