Poets and Writers
The Poets & Writers Database is an indispensable tool for finding literary magazines. It provides such essential information as whether electronic submissions are accepted, if simultaneous submissions are allowed, reading period, if payment is offered, and circulation numbers. You can filter magazines by poetry or fiction. Magazines are not ranked. So, if you want to know a magazine's standing in the literary world, check it against Clifford's list.
Poets & Writers is the nation's largest nonprofit literary organization serving poets, fiction writers, and creative nonfiction writers. Aside from their database of literary magazines, they post contests, conferences, agents, jobs, and many other valuable resources for writers. P&W is worth joining.
