Foundation: The International Review of Science Fiction is a critical peer-reviewed literary journal established in 1972 that publishes articles and reviews about science fiction. It is published triannually by the Science Fiction Foundation. The Encyclopedia of Science Fiction has called it "perhaps the liveliest and indeed the most critical of the big three critical journals". A long-running feature was the series of interviews and autobiographical pieces with leading writers, entitled "The Profession of Science Fiction", a selection of which was edited and published by Macmillan Publishers in 1992. Several issues have been themed, including #93, also published as part of the Foundation Studies in Science Fiction. The hundredth edition was unusual in that it was an all-fiction issue, including stories by such writers as Vandana Singh, Tricia Sullivan, Karen Traviss, Jon Courtenay Grimwood, John Kessel, Nalo Hopkinson, Greg Egan, and Una McCormack. Back issues of the journal are archived at the University of Liverpool's SF Hub whilst more recent issues can be found electronically via the database providers ProQuest.
