In this photo taken Wednesday, April 3, 2013, people are reflected in the windows of the British Library where old books are kept in London, Wednesday, April 3, 2013. Capturing the unruly, ever-changing Internet is like trying to pin down a raging river. But the British Library is going to try. For centuries the library has preserved a copy of every book, pamphlet, magazine and newspaper published in Britain. Starting Saturday, April 6, 2013, it will also be bound to record every website, e-book and blog, in a bid to preserve the nation's "digital memory." (AP Photo/Lefteris Pitarakis)
