'', by
Walter Jon Williams The first Nebulas were given in 1966, for works published in 1965. The idea for such an award, funded by the sales of anthologies collecting the winning works, was proposed by SFWA secretary-treasurer
Lloyd Biggle, Jr. in 1965. The idea was based on the
Edgar Awards, presented by the
Mystery Writers of America, and the idea to have a ceremony at which to present them was prompted by the Edgar and
Hugo Awards. The initial ceremony consisted of four literary awards, for
Novels,
Novellas,
Novelettes, and
Short Stories, which have been presented every year since. A Script award was also presented from 1974 to 1978 under the names Best Dramatic Presentation and Best Dramatic Writing and again from 2000 through 2009 as Best Script, but after 2009 it was again removed and replaced by SFWA with the
Ray Bradbury Award. In 2018, a new
Game Writing category was added, for writing in video and tabletop games. For the 2026 awards, two categories – Comics and Poetry – were added. Prior to 2009, the Nebula Awards employed a rolling eligibility system. Each work was eligible to qualify for the ballot for one year following its date of publication. As a consequence of rolling eligibility, there was the possibility for works to be nominated in the calendar year after their publication and then be awarded in the calendar year after that. Works were added to a preliminary list for the year if they had ten or more nominations, which were then voted on to create the final ballot. In 1970, the option was added for voters to select "no award" if they felt that no nominated work was worthy of winning; this happened in 1971 in the Short Story category and in 1977 in the Script category. Beginning in 1980 the eligibility year for nominations was set to the calendar year, rather than December–November as initially conceived, and the SFWA organizing panel was allowed to add an additional work. Authors were also allowed to use the mass-market paperback publication of their books as the beginning of their nomination period, rather than the initial hardback publication. As a consequence of the combination of this rule and the rolling eligibility, the 2007 awards, despite nominally being for works published in 2006, instead were all given to works initially published in 2005. Beginning with the 2010 awards, the rolling eligibility system and paperback publication exemption were replaced with the current rules. ==Categories==
