The current report on e-books from the Book Industry Study Group (BISG), released on 28 April 2011 has a lot of interesting information that can help to measure the "velocity of change" in the book industry as it relates to epublishing. BISG gives us a number of measurements on the magnitude (increased sales, higher percentage of readers) and direction (upwards). Taken together, I think it's safe to say that the velocity of change (in the ebook field) is rapidly increasing.
- 13% of print book buyers have downloaded an e-book
- 66% of respondents have moved mostly to e-books
- book sales have INCREASED in the past six months
A quote from Scott Lubeck (BISG Executive Director):
"This is a market in fast motion and identifying trends early is the key to gaining a competitive edge," said Scott Lubeck, BISG's Executive Director. "This on-going BISG baseline study of consumer behavior toward e-books and e-book reading devices is essential to understanding both the velocity of change and its significance to every stakeholder in the book industry."
