> it should be noted that libraries don't profit by rummaging through the books you read to advertise to you. They do present/display/advertise their most popular books. They track and fine you if you keep a book too long. They determine how much a book has been checked out and track usage at an analytics level to determine if the book should be taken out of circulation. Maybe search engines should have a special status like libraries enjoy, but it's worth noting the centuries it took for public libraries to become a municipal requirement.
