An anthology is a published collection of writings (such as poems or short stories) by different authors.
One of the basic characteristics of anthologies is that the works included are relatively short. They are good for days when focusing for a long time may not be feasible, or when one wants a literary bite before bedtime.
By definition, because anthologies include works by different authors, they include different voices, styles, and maybe genres. If you don’t like one story, move on to the next.
When anthologies draw from previously published sources, the work has already been vetted for quality more than once. Indeed, many anthologies are published annually with titles like The Best X Short Stories of (Year).
Anthologies can be selected by format. Most recent anthologies are available both as physical books and ebooks.
Anthologies are often broad in scope.

Some anthologies are mission driven. A couple of examples of these would be Drumvoices Revue (where my short story “Aunt Fan’s Private Journey” appeared), which celebrates diversity, and the Chrysalis Reader series, which describes itself as “original essays, poetry, and short stories illuminating the world of spirit.” One volume included my story “Solid Line.”
Sometimes they are focused by geographic region.
