A zine (short for magazine or fanzine) is a small-circulation, self-published work. Zines come in a variety of styles: photocopied, printed on cheap paper, or professionally printed. They could and were about any topic imaginable. My favorites were the punk and true crime-related ones. Extreme Noise in Minneapolis had a free zine bin that I happily dig through every time I visited and I'd leave with the most interesting ones. Zines were particularly popular in the mid- to late-1990s, and were later replaced by blogs and social media.
