Pew Internet & American Life Project. June 22, 2012.

Some 12% of Americans ages 16 and older who read e-books say they have borrowed an e-book from a library in the past year. Most e-book borrowers say libraries are very important to them and their families and they are heavy readers in all formats, including books they bought and books lent to them. E-book borrowers say they read an average (the mean number) of 29 books in the past year, compared with 23 books for readers who do not borrow e-books from a library. Perhaps more striking, the median (midpoint) figures for books reportedly read are 20 in the past year by e-book borrowers and 12 by non-borrowers. But most in the broader public, not just e-book readers, are generally not aware they can borrow e-books from libraries. [Note: contains copyrighted material].
