History of SFL
Science Fiction London (SFL) evolved out of an earlier club called Star Trek Ontario, founded in 1980 by a group of Star Trek fans. The inaugural meeting of Star Trek Ontario was March 17, 1980.
If you're interested in the early history of the club, check out Understanding Reality or Bust, which is a history of the club's first seven years. Although it is not available in bookstores, a few private copies exist among the senior members of the club and could possibly be borrowed from them.
