Digital publishing expert Colleen Cunningham has compiled an excellent list of ePublishing resources on the Digital Book World site (although it ignores QuarkXPress, which is among the best tools for creating ePubs).
The list is conveniently broken down into resources, tools, and quality assurance sections, and each of those are further divided by topic. The resources list alone is a goldmine, offering books, conferences, podcasts, and communities dedicated to the production of e-books. Read it at here.
Jay Nelson is the editorial director of PlanetQuark.com, and the editor and publisher of Design Tools Monthly. He’s also the author of the QuarkXPress 8 and QuarkXPress 7 training titles at Lynda.com, as well as the training videos Quark includes in the box with QuarkXPress 7 . In addition, Jay writes regularly for Macworld and Photoshop User magazines and speaks at industry events.
