I’ve been researching one QueryTracker which agents accept queries on short story collections and also on romances. One of these days, I’ll organize the stories into an anthology and query agents with it.
For anyone not familiar with QueryTracker, it’s a great resource and it only costs $25 a year. You can search agents and publishers (and find out which publishers accept unagented submissions). Each agent and publisher that’s listed has been checked out by the staff at QueryTrackerl. Each listing tells what genres the agent or publisher considers. And you can keep track of the agents and publishers you queried, the date and whether they accepted or rejected your query. There’s also a comments section for each agent and publisher where authors can post their experience with an agent or publisher.
