One of the several anthologies I have a short story in.
The world has changed. Selling our words is different now.And it's changing every day. The "old" rule was to not bother writing short stories if you wanted to make a living writing. Oh sure, you might write a few if you had a novel coming out, or for a friend's anthology, or a magazine you loved, but usually, don't bother. Or you'd bother if you were like me and loved writing short stories. But nobody, with a few exceptions, made a living writing short stories.The wisdom was: readers really prefer novels.
POD technology gets cheap.The e-book arrives and takes off. Turns out the "wisdom" was wrong. Turns out readers love to read short stories.When print was all there was it was difficult for readers to find magazines and anthologies, for they were few and far between and often expensive. Even single "famous" author collections were rare. But now many small publishers publish short stories, as a stand alone e-book or in an anthology, or both. Now there are a variety of online magazines, for all sorts of tastes, that publish short stories. Some of those magazines do both print and electronic, now.
This post came to mind because I'm doing a talk on "Selling the Short Story" to the Twin Falls Chapter of the Idaho Writers League. And boy, now the writer can really sell those shorts! I'm published/being published in several magazines/anthologies/e-book stand alones. Including a print version of a previously e-published short story by Big Pulp.
So write short and sweet and sell!
