Critical Mass was an Atlanta-based fanzine in the late 1980's. There were only ever three issues released. This particular issue is from January/February 1989, and is comprised of selected works produced by a group called The Science Fiction Writers of Cobb County (SFWCC), a collective that held its first meeting on May 17, 1984. As the name suggests, many of its members reside within Cobb county, though inclusion is not necessarily restricted to this criteria as others hail from different parts of the metro-Atlanta area.
