Nebula - The Nebula Awards are voted on, and presented by, full members of Science Fiction and Fantasy Writers of America and because of this voting body, the Nebulas are thought to be the most prestigious science fiction award.

Winners are included in the organization’s annual anthology; Willis was the editor of that anthology in 1999, the Nebula Awards 33. Every spring there is an banquet that is proceeded by meetings and panel discussions. The first awards were presented in 1965.
Hugo - The World Science Fiction Society began awarding the Hugo Awards in 1953. Named after Hugo Gernsback, the founder of the pioneering science fiction magazine Amazing Stories and considered one of the “fathers” of the science fiction genre, awards are given according to several different categories, including Best Novel, Best Novella, Best Novelette, Best Short Story, and new in 2017, the Best Series award was begun. The Society's members vote on the best science fiction or fantasy works of the previous year; the awards are presented at the annual World Science Fiction Convention.
