A colleague of mine directed me to an excellent site devoted exclusively to author videos called Meet the Author.
Here you can view a personalized video of your favorite author. The copy from the site says,
"The video clips are NOT reviews, they are NOT written by the marketing departments of publishers - these are authors speaking from their heart - to YOU.The site also has a Marketplace, where they tell you how to pitch your book idea to agents, publishers and readers by making a personalized video.
Meet the Author is updated daily..."
And lastly, the site has an Authors' Lounge, where published authors talk to you about their books and how and why they wrote them. Some of the authors include Patricia Cornwell, Preethi Nair, David Baldacci, and Tim Bowler among others.
Take a look and start promoting your work with a book trailer.
