The World Science Fiction Society (WSFS) is an unincorporated literary society whose purposes, according to its rules, are as follows: to choose the recipients of the annual Hugo Awards (Science Fiction Achievement Awards), to choose the locations and Committees for the annual World Science Fiction Conventions (the Worldcons), to attend those Worldcons, and to choose the locations and Committees for the occasional North American Science Fiction Conventions (the NASFiCs). A NASFiC is held in North America in any year when the Worldcon is outside of North America.
Almost all of the activities of the Society are performed by the selected convention committees, which are independent groups. Membership in the Society is defined as all persons for whom membership dues have been paid to the current Worldcon committee. The convention committees are selected two years in advance and you may wish to contact them as listed on this site for further information.
