NEW YORK » A new Pew study reports that around 13 percent of Americans aged 16 and older used a mobile device to visit a library website during the past year.

Patrons ages 18-49 were the most likely to use a mobile device for the library, while those 65 and older were the least likely. According to Pew, a 2009 University of Washington study showed 6 percent of those 16 and older using a mobile device to access a library site.

The latest survey from the Pew Research Center’s Internet & American Life Project was released today. Pew has been conducting a series of studies on e-books and e-reading devices.

The survey of 2,252 people was conducted via land lines and cellphones from Oct. 15 to Nov. 10. The sampling error margin is plus or minus 2.3 percentage points.
