1935–present) was formed. The next year, half a dozen fans from NYC came to Philadelphia to meet with the PSFS members, as the first Philadelphia Science Fiction Conference, which some claim as the world's first science fiction convention. Soon after the fans started to communicate directly with each other came the creation of science fiction fanzines. These amateur publications might or might not discuss science fiction and were generally traded rather than sold. They ranged from the utilitarian or inept to professional-quality printing and editing. In recent years, Usenet newsgroups such as rec.arts.sf.fandom, websites and blogs have somewhat supplanted printed fanzines as an outlet for expression in fandom, though many popular fanzines continue to be published. Science-fiction fans have been among the first users of computers, email, personal computers and the Internet. Many professional science fiction authors started their interest in science fiction as fans, and some still publish their own fanzines or contribute to those published by others. A widely regarded (though by no means error-free) history of fandom in the 1930s can be found in Sam Moskowitz's The Immortal Storm: A History of Science Fiction Fandom Hyperion Press 1988 (original edition The Atlanta Science Fiction Organization Press, Atlanta, Georgia 1954). Moskowitz was himself involved in some of the incidents chronicled and has his own point of view, which has often been criticized. By country Sweden Organized fandom in Sweden ("Sverifandom") emerged during the early-1950s. The first Swedish science fiction fanzine was started in the early 1950s. The oldest still existing club, Club Cosmos in Gothenburg, was formed in 1954, and the first Swedish science-fiction convention, LunCon, was held in Lund in 1956. Today, there are a number of science fiction clubs in the country, including Skandinavisk Förening för Science Fiction (whose club fanzine, Science Fiction Forum, was once edited by Stieg Larsson, a board member and one-time chairman thereof), Linköpings Science Fiction-Förening and Sigma Terra Corps. Between one and four science-fiction conventions are held each year in Sweden, among them Swecon, the annual national Swedish con. An annual prize is awarded to someone that has contributed to the national fandom by the Alvar Appeltofft Memorial Fund. UK SF fandom in the UK has close ties with that in the USA. In the UK there are multiple conventions. The largest regular convention for Literary SF (Book focused) fandom is the British National convention or Eastercon. Strangely enough this is
