There's a new industry in the making. It's in the way we buy and read books. Electronic books, or e-books, are taking the book market by storm. Here's a mind blowing statistic. Barnes & Noble (BKS) announced that in December its e-book sales exceeded print books, as reported in MSNMoney.

The two big leaders in the e-book market are Amazon.com (AMZN) and Barnes & Noble with the Kindle and Nook readers respectively. Both companies said that e-readers are their best-selling product of all time.

Rumors have been circulating for almost a month about Borders' (BGP) possible bankruptcy filing. People familiar with the situation told The Wall Street Journal that the filing could come as early as the middle of this month.

Borders has been trying to hold off the filing by delaying payments to vendors. But this is only temporary. Now the matter has reached a critical stage. The company has obtained about $500 million to $550 million in debtor in possession financing that would keep the company operating after a court filing.

When there's uncertainty to a thesis, I'm not inclined to buy. That might seem obvious on the surface, but I know there are a lot of individual speculators out there who would disagree with me. Take a roll of the dice, they might say. Uncertainty can lead to huge gains, they might counter. Well, it depends on the situation, I suppose. In the case of Barnes & Noble, Inc. (BKS), I think I'll take my chances elsewhere.

At the time of this writing, shares of the bookseller were off by more than 4% in the afternoon session, coming in at $14.36. Volume wasn't yet above average, however.

Barnes & Noble Inc. (BKS), the New York-based bookseller and purveyor of the Nook digital book reader, is scheduled to release its fiscal fourth-quarter 2010 financial results after the market closes Monday, June 28, and to discuss those results in Tuesday's Investor's Day meeting (webcast) beginning at 9:00 AM (ET).

During the three months that ended in April, Barnes & Noble appointed a new CEO and announced new features of its Nook e-reader. Analysts surveyed by Thomson Reuters expect the largest bookseller in the U.S. to report a net loss of $0.81 per share, deeper than the year-ago loss of $0.04 per share. Yet, its revenue is expected to have risen 16.1% from a year ago to $1.3 billion.
