Merlin was a science fiction fanzine by Lee Anne Tremper, now Lee Anne Lavell.
Merlin was published in the 950s in Indianapolis, Indiana, U.S.A. It began life as ISFANEWS, the club zine for the Indianapolis Science Fiction Association. As Lee Anne writes in Askance #9, from July 2008, "It was a one and half page thing that was mostly meeting notice although I did manage to pick up a column in its later days." "...Isfanews started getting contributions and I changed the name to Phobos, a bi-weekly eight pager that rather quickly got overwhelming, so on came another change to Merlin which, while later, came out only monthly."
At least 12 issues of Merlin appeared in 1954 and 1955.
One issue featured the story "The Sirens of Space" by Dave Jenrette, which was later republished in Infinity Science Fiction.
