More and more books digitally published

A shrinking economy and rising technology have transformed how, and how many, books are being published. But the number of “on-demand” books, a category featuring works with tiny, digitally stored print runs, topped 285,000 in 2008, the first time they outnumbered traditional texts. In 2006, there were fewer than 22,000 on-demand titles, which have become an increasingly popular way to bring old books back in print or keep recent releases from going out of print.
