Two digital publishing sites have quietly started rolling out electronic books that can be viewed just using a web browser.
Random House is now offering several full length books for free on Scribd. The choices include The Surgeon, a 2002 novel by bestselling author Tess Gerritsen. What's also significant here is that Gerritsen is making the book available as a DRM-free PDF download.

Meanwhile Zinio, a site that offers digital magazines and textbooks, is expanding into mass-market books. Zinio has opened a digital bookstore that features a handful of titles. These include technology tomes like Social Media Marketing in an Hour a Day.
It's great to see the publishing industry experimenting with new formats. I personally think that book publishing is primed to see the same kind of disruption that the music business saw earlier the decade. This is why I am a fan of sites like Safari Books Online.
As mobile devices become more sophisticated, many consumers will aspire to do more in their browsers. This includes, for some, reading books. I think this will lead to a lot of experimentation with different business models. Two that come to mind are a-la-carte pricing for specific chapters and/or books that are free and supported through advertising.
Scribd, which has seen strong growth this year, and Zinio won't be alone. Google could start monetizing out of print books or even current bestsellers in a manner similar to what it has done with magazines. In addition, I would be highly surprised if by year's end the Amazon Kindle wasn't just a gadget but a platform that operates on many devices, including most mobile phones. They will increasingly face pressure from the iPhone.
It's early going and electronic reading is not for everyone. However, millennials and their younger sibings expect all media to be searchable and available in chunks. So this is why I am bullish about ebooks and think they will have a breakout year in 2009.
