If you’re in the submission slush like I am, and you don’t have the cash to buy the Writer’s Market directory or pay for membership at Duotrope, then here is the answer: The Grinder!
Their mission as stated by them:
The grinder is a submission tracker and market database for writers of fiction (non-fiction and poetry coming soon!). Use our extensive and powerful search engine to find a home for your work. With new features being added periodically we hope to provide a permanent and stable home for your submission tracking.
We believe the value of our product lies in its availability and as such The Grinder is and always will be free to all users for all features.
The searchable database allows you to pick genre (Fantasy? Sci FI? Horror? Lit?), Pro/Semi-Pro markets, and gives the details of writer’s experiences. If you’re looking for new journals/ magazines this is a necessary stop!
