This category is for "one-shot" or "stand alone" anthologies of science fiction which are collections of stories written by multiple authors, but in which the stories do not have a shared universe, or other unifying theme (Best of year collections, Best of Magazine, etc.).

• When such a collection is issued in multiple volumes over a period of time, it becomes an anthologies series, and should be categorized instead in the sub-category Category:Science fiction anthology series, or one of its sub-categories.
• Single author collections, including some considered as a series (e.g. Niven's Known Space collections) also go in the appropriate sub-category'... Category:Science fiction short story collections (for single author collections.)
