I get asked all the time why I have an agent when so many of my books are published by epublishers. Because you can still land ebook deals without an agent (and because epublishers often pay very small advances, or none at all), many people think you shouldn't bother getting an agent.
Based upon my experience, I would disagree. Saritza Hernandez, a staffer at the L.Perkins Agency where I'm a client, specializes in the ebook market, and she recently wrote this blog post about why you might need an ePub agent. Thought I'd share.
