The percentage of book buyers who reported downloading an e-book rose from 5% in October 2010 to 13% in January, according to the latest installment of Book Industry Study Group's "Consumer Attitudes Toward E-Book Reading" survey. The survey also found that among readers who have moved to digital reading about two-thirds said they mostly or entirely read e-books. E-book readers also reported buying more and spending more on books overall in the last six months, with 44% of responding e-book buyers saying they inceased unit purchases and 34% reported higher overall spending on a combination of e-books and print books.
