Someone asked me recently if I had any info on how to find an agent. So, here you go:
Research agents and editors. You need to know who you're querying.
It's best to have a personal connection to the agent or editor, e.g. an author friend recommends you or you meet the agent or editor at a conference or book-signing.
If you don't have a personal connection, don't worry! There are many online resources, including:
Free searchable Agent database.: http://agentquery.com
Free searchable agent/editor database: http://www.querytracker.net.
Free List of Association of Author's Representatives: http://aaronline.org/Find.
Free Absolute Write discussion forum:http://www.absolutewrite.com/forums
not-free Publishers Marketplace where you can track deals, sales, agents, editors:
Always double-check agent's or editor's webpage to make sure what they want in a query now.
And the baddies are announced here:
Preditors and Editors http://pred-ed.com
Some successful query letters with agent responses can be found here:
