E-book Sales Surpass Hardcover Books

Monday was a day for the history books — if those will even exist in the future. Amazon.com, one of the nation’s largest booksellers, announced Monday that for the last three months, sales of books for its e-reader, the kindle outnumbered sales of hardcover books. In that time, Amazon said, it sold 143 Kindle books for every 100 hardcover books, including hardcovers for which there is no Kindle edition.
