You DEFINITELY want to target your agent queries. In other words, don't query an agent who is only interested in self-help books with your children's book idea! It's a waste of their time--and yours.
Pick up a copy of Writer's Market in a bookstore and study the agent listings for those actively seeking titles like yours. Then go to their website, if they have one, and look at their most recent sales. All agents want to see that you're specifically targeting them and that you know who they are and what they represent.
Also, pay close attention to their submission guidelines. Some ONLY accept email queries and want specific things in the subject line, etc. And most will noteven open an email with attachments, so be careful about that.
Another good idea is to pick up books similar to yours that have been published in the last year or so. Look in the author acknowlegements. Authors
always thank their agents. This is another good way to produce a shortlist of agents who you know represent books like yours.
Good luck!
