When I contacted Chris Barton (author of The Day-Glo Brothers, Shark vs. Train, and the soon-to-be-released Can I See Your I.D.?), he replied that he didn't have time to write up a post. But, gracious Texan that he is, he didn't leave me empty-handed.
Last August, Chris did a Writer's League of Texas panel on book marketing. And it's all available on YouTube. So here is a ton of great information from a group of publishers: what they do and what you as an author can expect to do to market your book.
It's a 12-part series; if you're interested in the rest, go here for part 4.
If you are a published author and you would like to share your experiences with marketing and promoting your book(s), I'd love to share your story! Please contact me at anpstevens [at] gmail [dot] com.
