I need some advice about a piece I wrote...

20. There's Duotrope, $50/year I think. Every Saturday they send you a list of markets. You can keep track of your subs too

There's a Facebook group, Open Call, that has posts about markets.

If you make short books or collections for Amazon, as some have suggested, you can promote them on places like StoryOrigin and BookFunnel, where you can offer people a free story to sign up for your newsletter or direct them to your books on Amazon.

And Writer's Market too is a good source.

Good luck!
