A recent sales report from Amazon.com indicates hard bound books may be becoming a thing of the past.
Amazon reported that electronic books or e-books outsold hardcover books by almost 50 percent.
In June, Amazon sold 180 e-books for every 100 hardcover copies. Paperback sales were not included.
"I think the thing that's compelling to most people is it sounds like the beginning of the end," Joseph Janes, an associate professor at the Information School at the University of Washington to National Public Radio.
Jones said the move to e-books is just a process of going into a full digital age.
"It's going to be a halting but probably steady forward path toward digital versions of what we used to think of as books," Jones said. "For a lot of people, if you can bump up the font and adjust the lighting, for people with reading impairments or just old eyes, some of these digital readers are a godsend."
E-books haven't been around all that long. The increased demand may be the result of a recent price cut.
Still, the hardcover book is far from extinct. Industry-wide sales are up 22-percent this year.
