Cambridge, Massachusetts, home of the world's prestigious universities -- Harvard and Massachusetts Institute of Technology (MIT) -- topped the list of the most well-read U.S. cities, an online report by CNN said Friday quoting Amazon.com

Amazon compiled its sales data for books, magazines and newspapers -- both in print and for its Kindle e-reader -- from Jan. 1, this year.

The bookseller used population figures to find out which cities bought them the most, per capita, CNN reported.

"The list not only considers where people are heavy readers, but where they opt to buy books online as opposed to at more traditional stores," CNN reported.

The top five were all college towns.

Cambridge was followed by Berkeley, California, Ann Arbor, Michigan, and Boulder, Colorado, along with Alexandria, Virginia, a suburb of Washington D.C.

"We hope book lovers across the country enjoy this fun look at where the most voracious readers reside, and that everyone gets the chance to relax with some great summer reads," Mari Malcolm, a managing editor at Amazon, said in a news release.
