Mike Gunderloy founded Factsheet 5 in 1982. Today on his personal website, he calls it "the stupidest time-saving idea I ever had," somewhat in jest. Under Gunderloy's control, it grew from a two-page photocopied sheet to a good-sized zine packed full of reviews each issue. At first it reviewed everything under the sun, but soon became focused on zines and the small press. With this transformation and development, Facsheet 5 became the first major zine review zine.
Cari Goldberg Janice joined F5 in the late '80s and became co-editor, Gunderloy and Goldberg Janice co-authored "The World of Zine" for Penguin Books in 1991. The books compiled some of their favorite zines from the pages of F5. Soon after the book was published and the zine scene was exploding, Gunderloy had a nervous breakdown just as the spotlight was on him. He quit Factsheet 5, stopped talking about the small press, and became a computer programmer. After Gunderloy quit, Hudson Luce produced one issue, then R. Seth Friedman continued the magazine (with contributing editor Chris Becker) until it ceased publication in the late 1998.
During the last '80s and '90s Gunderloy also wrote a lot of articles about zines and the small press, as well as review, including fairly frequent contributions to The Whole Earth Review. In one article Gunderloy described zines to the general public:
"Zines are the periodicals that live in the cracks between the major journals you can find on the newsstands. They are published all over the country, circulate primarily by mail, and are done for love rather than money. Because they're hobbies rather than businesses, zines can be freer in what they say. But this also means you have to be more patient in dealing with them. The typical zine publisher comes home after a long day at some real job and then spends another six hours writing, designing, and trying desperately to answer her mail. Be patient when you write. Send a stamped, self-addressed envelope if you want more information. Send well-wrapped cash, or checks made out to the person doing the publishing rather than the name of the zine, which probably doesn't have a bank account. And above all, be prepared to be surprised, entertained, outraged, amused and informed by these, the irrepressible outlaw publishers of the world."
