Digital Books vs. Traditional Books

        Printed books have a growing competitor in ePub or digital books.  Helping us keep informed about this we hear from Jim Hamm.  He asks, "Want to download and read a book on your Mac? The TidBITS Newsletter brings forth an ePub reader for the Mac. Here's two articles that offer more info on this."  This one is from Macworld. 
       Here's a video talking about the publishing of e-books, as compared to traditional books.  Jim comments,"I found it interesting to hear how the two models compare, particularly from the perspective of authors."
