The New York Public Library says it is “making 700 books — from classics to current best sellers — available to members in digital audio form for downloading onto PCs, CD players and portable listening devices. Users can listen to digital audio books through a computer, burn them to CDs or transfer them to many portable devices, library officials said. Digital audio books are available for free to members through the library’s Web site. Users can borrow up to 10 digital books at a time, and after 21 days the materials will be automatically checked in and made available to others.”
