Resources
Here are a few of the most reliable sources I’ve found for OER fiction:
Project Gutenberg – Free texts by writers who have passed into the public domain
Open Culture Free e-books by non-living but in some cases modern writers
The New Yorker (this one is tricky, as you can only access so many stories per month)
There are many online sources that offer free texts, but you have to register. I did not include these in this list or anthology.
