Always verify agent's information before sending your query, and review the agent's website(s) for more up-to-date information.

Though we do our best, QueryTracker can not guarantee the accuracy of any information provided.

An agent listing on QueryTracker is not an endorsement or recommendation of that agent by QueryTracker.

Before contacting an agent, authors should verify and assess the agent's requirements and suitability by visiting the agent's website(s), and becoming familiar with ways to spot and avoid bad agents. A good place to start is Writers Beware, a watch group that helps inform and protect authors from shady practices.
