SWILL was fan magazine created in February 1981 in response to the controversy created within Ontario science fiction fandom by a fake boycott poster distributed at the 1979 Maplecon by Neil Williams. Because of this controversy, the SWILL was published in 1981. A successor magazine; Daughter of Swill, Mother of Scum was published in 1984 and 1985. The twentieth anniversary was marked by the publication of the online magazine SWILL Online in 2001. The magazine was revived in 2011 for its thirtieth anniversary and continues to be published (with some publication hiatuses). The most current issues are available online and the publisher's website. SWILL 2015 has not been previously published in book form. SWILL 2015 contains issues #27 through #30 of SWILL.
