great resource to find information about new books, old books, and upcoming books; Electric Literature is also a great place to find short stories. Their "recommended reading" section has great short stories; or you can find "poetry, essays, and graphic narratives" in "The Commuter." Electric Literature is a nonprofit, and much like Narrative they work hard to promote new and emerging writers.
WATTPAD
Wattpad is a reader/writer interface that allows people to easily access over three million different stories through their website, or by downloading the app. It's also a great place to submit short stories if you're interested in writing. The site is open to anyone, at any level of writing experience. If you're more interested in reading than writing, topics range from adventure to teen fiction to fan fiction to poetry and horror. There's a little bit of something for everyone.
