And the Borders idea is a good one. I also remember my Dad used to have a book called something boring like The Writer's Digest that listed names and addresses of publishing companies along with what kind of books they handled...also had tips on getting published.
I wonder if they still make that book?
There's a series called, IIRC, "Writer's Market" that has volumes aimed at most major genres. Probably a version for the children's market, too. Definitely should be at Borders.
