SFA

Also an abbreviation for the Science Fiction Advertiser.

from Fancyclopedia 2 ca. 1959

The Science-Fiction Association, an organization with HQ in Great Britain which arose in 1937, held three conventions ("annual meetings") each more successful than the last, and went dormant with the outbreak of World War II. (Unlike the BFS, it could not carry on its official business without the members of the Council meeting in person.) The founders and leaders of the SFA were those whom Webster calls First Fandom; some Americans were members.
