2-5YM is a Star Trek: TOS club zine
About: From the Editor
Once upon a time, a very long time ago now, about 1973, I read about the existence of something called Star Trek fanzines in a couple of books by David Gerrold, most notably The World of Star Trek. In November or December of that year I put together my own zine, 2-5YM, which was short for Second Five-Year Mission, something we Trekkies all longed for back then. That five page ditto led to my meeting my friend, a young English teacher who later became a librarian. Soon we merged with STAR Syracuse, the local Trek club. We continued to publish 2-5YM until 1977, by which time it was published by offset press, if I recall correctly. At least a few issues in between were done by mimeo, typed for us by a little old lady in Fayetteville.
