The World Science Fiction Society is an unincorporated literary society whose purpose is to promote interest in Science Fiction. WSFS has no standing officers, only small standing committees, and a large membership composed of the members of the current Worldcon. Running that convention, and awarding the Hugo Award, are its main activities. It also awards the John W. Campbell Memorial Award for Best Science Fiction Novel and Best New Writer.
