Tulane Univ. has announced they are increasing the number of textbook titles available in digital format.

The article contains a curious irony. It states:
"To download the book, a computer or reading device like the Kindle, which has a starting price of about $300, is also necessary."
At the bottom of the article, however: "The Tulane University Bookstore is a Barnes and Noble college store location."
One wonders about the formats and DRM for the textbooks.
