A new study released on Thursday by the Pew Internet & American Life Project found that while there are more Americans who read e-books as ownership rises of digital readers like Kindle, few have come to rely on e-books exclusively.

The percentage of Americans who read e-books has grown to 28 percent by the end of 2013, compared to 23 percent in 2012. However, only four percent said that they only read e-books, as opposed to print editions and audiobooks.

The study shows Americans’ diverse reading habits, with 70 percent still reading print editions of books and 14 percent listening to audiobooks. Those who listen to audiobooks tended to read books in all of the formats, while those who liked print editions tended to stick just to ink and paper.
