Writer’s Market - Seeking an Agent

I assume you're looking for an agent because you want a Big-5 publishing contract. You should research agents carefully re their track record in that regard. The only advantage of snaring an agent is to get that elite contract. Medium-size publishers usually don't require an agent middleman; in fact, some prefer you don't have one. Several years ago I did the agent research thing, narrowed them down by expressed interest in my genre and proven track record. I sent out dozens, if not hundreds, of queries. Less than half bothered to reply at all. Of those that did respond, they did so with boiler plate rejections. Occasionally, I received a reply that addressed the actual query, explaining the reason for the rejection. Those were my favorites. Eventually, I gave up looking for an agent and went directly to publishers. Goodness knows I wouldn't mind having an agent that could get me an advance with Putnam or the like, but until then I've got a publisher who is author-friendly, is sticking with me, and has offered to renew the  contracts for my earlier books. Good luck with your search. You might get in touch with GPyrenees- who did find an agent back in the day - for tips.
