 Beside the Nebulas, several other awards and honors are presented at the Nebula Awards ceremony, though not necessarily every year. Two of them are annual literary awards voted by SFWA members on the Nebula ballot: the Andre Norton Award for Outstanding Young Adult Science Fiction or Fantasy Book, inaugurated 2006, and the Ray Bradbury Award for Outstanding Dramatic Presentation, which replaced the Best Script award in 2010. The others are the Damon Knight Memorial Grand Master Award since 1975 for "lifetime achievement in science fiction and / or fantasy", the Author Emeritus since 1995 for contributions to the field, the Kevin O 'Donnell, Jr. Award for service to SFWA, and the Kate Wilhelm Solstice Award since 2009 for significant impact on speculative fiction. All four are discretionary but a Grand Master, selected by the officers and past presidents, has been named every year for more than a decade. The Solstice Award may be presented posthumously (where only living writers may be named Grand Master or Author Emeritus); in all, twelve have been awarded in five years to 2013.
