Duotrope

Duotrope is an established, award-winning resource for writers and artists. We help you save time finding publishers or literary agents, so you can focus on creating. Our publication and agent listings are up to date and full of information you won't find elsewhere. We also offer submission trackers, several search options, theme & deadline calendars, statistics on publishers, and extensive interviews.

Duotrope is a subscription service, but if you're actively looking for publishing opportunities, it's worth every penny.
