Find Agents at LitMatch

There's a new free service for book writers: LitMatch - Literary Agent Database and Online Query Tracking. When I just checked, they boasted, "Listing 1680 Agents in 770 Agencies." Better yet, the site's search engine allows you to zero in on specific agent and agency details. You can search by location, many genres, whether they're currently accepting queries, have a blog, website, or membership in AAR, and whether or not the agent has updated the listing. You can also find an agent or agency by a single field, or any combination of fields. For example, I looked for agents in San Diego who handle nonfiction. I like the sort results feature that allows them to be grouped by agency (why bother the same agency by contacting different agents there about the same MS?) I haven't tried the tracking part, but owner Chris Hawkins has some interesting, relevant posts on the service's blog.
