Click by Click, Libraries and Readers Wade Into Digital Lending

"About 5,400 public libraries now offer e-books, as well as digitally downloadable audio books. The collections are still tiny compared with print troves. The New York Public Library, for example, has about 18,300 e-book titles, compared with 860,500 in circulating print titles, and purchases of digital books represent less than 1 percent of the library’s overall acquisition budget. But circulation is expanding quickly. The number of checkouts has grown to more than 1 million so far this year from 607,275 in all of 2007, according to OverDrive, a large provider of e-books to public libraries. NetLibrary, another provider of e-books to about 5,000 public libraries and a division of OCLC, a nonprofit library service organization, has seen circulation of e-books and digital audio books rise 21 percent over the past year."
