Full Name	Nebula Awards
First year given	1966, for works published in 1965
Who	The Science Fiction and Fantasy Writers of America
What	Lucite trophy, originally designed by Kate Wilhelm and Judy Blish
Where & When	Annual Nebula Awards banquet, site varying each year, held usually in April or May
Scope	Works published or released in the US
Categories	Novel, novella, novelette, short story; in some years, screenplay
Eligibility period	Currently, the two calendar years prior to year of award. A work may accumulate member recommendations for 12 calendar months following publication. For example, a work published in July 1998 may gather recommendations until June 1999; if it gathers 10, it is placed on the preliminary ballot for awards given in 2000.
Dating convention	Year prior to award (in 2001, SFWA awards the 2000 Nebulas, covering works published in 1999 and 2000)
Issues and controversies	The Nebulas' 12-month eligibility period has the effect of delaying recognition of many works until nearly 2 years after publication, and throws Nebula results out of synch with other awards (Hugo, Locus) voted in a given calendar year. Though the Nebula Awards ostensibly honor works published in the US, they rarely honor non-US writers (Ballard, Priest, Egan, et al), even those frequently published in the US.
Type	Two-stage ballot
Process	All works receiving a minimum number of member recommendations (10) are placed on a preliminary ballot; members vote on this to determine a final ballot, to which a jury may add one work per category; members vote on the final ballot to determine winners
Comments	SFWA releases preliminary ballots, but only final ballot nominations are included in this database.
