Amazon Original Stories has been publishing a series of projects over the last several years that they call “collections,” but which I always think of as “deconstructed anthologies.” They’re clearly assembled as anthologies—and feature short works by multiple authors—but the stories are all downloadable individually, rather than together as a single book. Since “collection” is typically used to refer to a single-author collection—a book of short stories that is comprised only of a single author’s work—it seems imprecise to use that terminology for the Amazon Original Stories publications. I may be the only one who will ever call them deconstructed anthologies, but in my mind that’s clearly what they are.
I’ve taken to using the phrasing “presented by” (rather than “edited by”) in situations such as this where you have a book of short stories that is clearly an anthology, but it is published in such a way that does not credit an anthology editor. In some cases, such as this one, an organization is credited; other times, there is only a publisher.
