Harlan Ellison has received the most Hugos for Best Short Story at four, Arthur C. Clarke, Larry Niven, Mike Resnick, Michael Swanwick, and Connie Willis have each won three times, and Poul Anderson, Joe Haldeman, Naomi Kritzer, and Ken Liu have won twice, the only other authors to win more than once.
Hugo Award nominees and winners are chosen by supporting or attending members of the annual World Science Fiction Convention, or Worldcon, and the presentation evening constitutes its central event.
The selection process is defined in the World Science Fiction Society Constitution as instant-runoff voting with six nominees, except in the case of a tie.
[4] Initial nominations are made by members in January through March, while voting on the ballot of six nominations is performed roughly in April through July, subject to change depending on when that year's Worldcon is held.
[10] In the following table, the years correspond to the date of the ceremony, rather than when the short story was first published.
