Nemonymous was a short fiction publication that labeled itself a "megazanthus" (a portmanteau of magazine and anthology). It was published in the United Kingdom from 2001–2010, and edited by British writer D. F. Lewis.
This publication was distinctive in that all stories were published anonymously, with the identities of contributing authors being normally withheld until the following issue, an arrangement intended to temporarily strip the reader of any prejudices surrounding the author's name (including popularity, gender and place of origin), and thus level the playing field for the writer. (Later issues did not follow this exact model.)
The first issue of Nemonymous, subtitled A Journal of Parthenogenetic Fiction and Late Labelling, appeared in November 2001. Nine issues were published through July 2010. The final four editions were more like books than journals: Zencore (2007), Cone Zero (2008), Cern Zoo (2009) and Null Immortalis (2010).
All stories saw their first publication in Nemonymous. A few notable republications after appearing in Nemonymous: "The Assistant To Dr Jacob" by Eric Schaller and "England and Nowhere" by Tim Nickels were chosen for Year's Best Fantasy and Horror anthologies. "Scenes From an Unfinished Film" by Gary McMahon was chosen for Year's Best Dark Fantasy & Horror. "The Lion's Den" by Steve Duffy was chosen for The Weird edited by Ann and Jeff VanderMeer.
Two stories apparently remain anonymous in perpetuo: the influential "Vanishing Life and Films of Emmanuel Escobada" and "George the Baker." Also, Nemonymous Two in 2002 is reputed to have published the world's first blank story. And Nemonymous Six existed only through its non-existence, according to records.
