The first British edition was published in trade paperback and ebook by Robinson in February 2012 under the alternate title The Mammoth Book of Nebula Awards SF.

[1] The book collects pieces that won or were nominated for the Nebula Awards for best novella, novelette and short story for the year 2010, profiles of 2010 Grand Master winner Joe Haldeman and Author Emeritus Neal Barrett, Jr., and representative early stories by each, various other nonfiction pieces and bibliographical material related to the awards, and the three Rhysling and Dwarf Stars Award-winning poems for 2009, together with an introduction by the editor.

Kirkus Reviews commended the book to "readers who like their fantasy and science fiction short and punchy," calling Paolo Bacigalupi's contribution "[t]he best of a spiffy bunch," as well as singling out Kosmatka's, Bakers, Johnson's, Foster's and McIntosh's pieces for special comment, while rating the remainder "[n]o less worthy.

"[2] Regina Schroeder in Booklist rated the volume "[u]nsurprisingly, ... an excellent collection of thought-provoking, entertaining, and varied work from both masters at the height of their careers and rising stars," and "a pleasing cross-section of what the genre has to offer."

[3] Jackie Cassada in Library Journal, citing the anthology's "strong and varied selections," felt "this serves as a top-notch introduction to the genre for newcomers and seasoned readers alike."
