Andy Ross, at Andy Ross Literary Agency, recommends checking out these sources:
- Association of Authors’ Representatives, a professional organization of more than 400 agents.
- AgentQuery.com, “The internet’s largest free database of literary agents.”
- QueryTracker.net, a database of 1,392 agents.
Andy also has a terrific blog, which includes a feature called “Ask the Agent” with information about what a literary agent does and how to work with an agent.
Another option is subscribing to Publishers Marketplace ($25/month), which tracks deals, sales, reviews, agents, editors, and news.
