Factsheet Five is a periodical originally published by Mike Gunderloy of Albany, New York. It consisted almost exclusively of short reviews of privately produced printed matter, along with contact details. In the early 1990s, its comprehensive revies, that ran into the thousands in any issue, made it the most important publication in its field, heralding what would eventually be called zine culture. Prior to the wider adoption of the web & e-mail around 1994/5, publications such as this formed a vital directory for connecting people of like-mind; for instance, in the queer 'zine culture of the late 1980s and early 1990s.
