Buying books online is too easy. Even if you don't have a clue what you want to read, there's always a software agent to suggest something based on your previous purchases or considerations. LA-based artist Angie Waller is putting this information to the test with her new book 'Data Mining the Amazon.' In it, she catalogues and graphs relationships between books and music bought on Amazon.com. Focusing on political icons in the US and abroad, the results are fascinating. For instance, visitors who bought 'All the Best, George Bush' tended to purchase CDs by Creed. Research also shows that readers of Hitler's 'Mein Kampf' were often fans of the Australian 70s band the Bee Gees.
