What the heck is zine, you might ask? Typically pronounced "zeen," these can take many different forms but the word typically describes some kind of printed pamphlet or booklet created in a DIY format by the artist, without intercession from a publisher or overarching profit motive. These might be made using a photocopier or done in a more artistic style on a risograph or using screen printing. A zine can be made on whatever topic you want or no topic at all.
