This one's complicated!
It was originally was a clubzine named Bulletin of the Cleveland Science Fantasy Society, (unsurprisingly for the Cleveland Science Fantasy Society). After becoming editor in 1952, Ellison published five issues as a clubzine before changing the title to Science Fantasy Bulletin (published through Fanvariety Enterprises) to show that it had become his own fanzine. After changing the title, he published nine issues through 1954. The last three issues were again renamed, this time to Dimensions. The last issue was published in 1957.
Honey Wood was a long-time senior staff member.
