The Writing for Dollars site has a harvest basket full of great archived articles. I read one recently entitled:
Getting Your Children's Book Reviewed.
Author Kathryn Lay enlightens us on this topic by giving insider tips from librarians and other publishing industry sources. While the tips are aimed at children's authors, some of what Ms. Lay mentioned applies to those writing for adults, too. She includes links and helpful background info for a well rounded, informative article. While at the Writing for Dollars site, sign up for the weekly newsletter if you are so inclined. It's a great resource.
Happy writing! :)
