I suppose everyone has their own way of defining these things, and some people get more determined about it than others, and some even strident. You’ll have your own opinions, and that’s fine, I’m just giving these the way I see it so you’ll understand my next three Friday posts. If you want to disagree in the comments, go ahead, I’m not going to argue with you.
So, in alphabetical order:
Anthology – a group of stories by different authors, edited, often with a specific theme, time period, or intent to group the stories cohesively. Example: The Hard-Boiled Veldt: Murder at the Water Hole, edited by Flinky Flanders.
Collection – a group of stories by a single author, edited by that author or another person. Could be a “best of”, several early or current works, something themed, or a “complete” set. Example: The Complete Stories of Flinky Flanders.
Omnibus – a group of two or more novels or other long works by a single author or by authors connected by subject, theme or time. Example: Three Early Novels of Flinky Flanders.
So that’s it, simple enough, works for me. For the next three Fridays I’ll be posting one of each.
