At this time, The National Fantasy Fan, Tightbeam, Origin, and The N3F Review of Books are published monthly. N’APA and Ionisphere (note spelling) are bimonthly. Eldritch Science is published at least once a year. Films Fantastic and Mangaverse are published irregularly.
Submissions for The National Fantasy Fan are due on the 15th of the month preceding publication. TNFF is usually assembled on the following weekend, which is a hard deadline. Submissions after the due date will be be held for the next issue. (Full submission guide here: http://n3f.org/zines/submissions/)
All issues of TNFF include artwork, Bureau reports, letters of comment on past issues, editorials, and plans for future issues. Support in maintaining convention listings would be appreciated.
The September TNFF is the election issue, with the call for elections. The ballot will appear in the October issue. Election results will appear in the December issue.
The Kaymar, Franson, and Neffy ballots and awards as appropriate will be announced in a timely way.
Timelines for issues of Tightbeam and for other special issues and projects will be announced in TNFF.
