Trap Door is a science fiction fanzine by Robert Lichtman. As of March 2012, a total of 28 issues have been published. It was nominated for a Hugo award for Best Fanzine in 1987 and 1992, but did not win (probably due to its low circulation).
Previously Robert Lichtman had published Psi-Phi in the 1950s and early 1960s, Frap in 1963 and 1964, and 100% Whole Wheat in 1965 with Miriam Knight (formerly Miriam Carr, now Miriam Lloyd) (Klein Bottle, A Funny Thing Happened On The Way To Poughkeepsie). After a period of being away from fandom he returned in the 1980s and began publishing Trap Door in 1983 in Glen Ellen, California, U.S.A. He is a longtime member of the Fantasy Amateur Press Association (FAPA), with his current membership starting in 1984 (and a previous one from 1962-70), and has served as its Secretary-Treasurer since 1986. He's also a member of long standing of the Spectator Amateur Press Society (SAPS), his current membership dating from 1982 (and previously from 1959-65).
