Nebula-palkintoa jakaa Science Fiction and Fantasy Writers of America. Nebuloita jaetaan viidessä eri kategoriassa: romaani, pienoisromaani (”novella”), pitkänovelli (”novelette”), novelli (”short story”) ja käsikirjoitus.
Palkinnon voittajan äänestävät SFWA:n jäsenet. Ehdokkaat valitaan jäsenten suositusten perusteella ja ensimmäisen äänestyskierroksen perusteella ehdokkaat karsitaan viiteen. Erityinen raati voi tarvittaessa lisätä listalle kuudennen ehdokkaan, jos kokee jonkun erityisen hienon teoksen jääneen unholaan. Näistä ehdokkaista SFWA:n jäsenet äänestävät lopullisen voittajan.
Ehdokkuus ei perustu tiukasti julkaisuvuoteen, vaan teosta voi ehdottaa listoille vuoden ajan sen julkaisemisesta. Periaatteessa siis kukin teos voi olla ehdolla julkaisuvuotenaan ja sitä seuraavana vuotena.
Lisätietoja löytyy palkinnon kotisivulta.
