These, unfortunately, are the easy questions, readily answered by throwing money at them. The difficult questions are just now becoming apparent. Our background as librarians may have given us a false sense of security that has obscured the urgency of this question. Right now, in most cases, we and our patrons can still move in and out of libraries anonymously, roam stacks freely without informing anyone of who we are or why we are there, and peruse books and magazines without having our actions recorded.
Public computers are usually available to patrons anonymously, as well.
But we are probably swimming against the tide. The loss of privacy not only facilitates the government's censorship efforts, but leads to widespread malaise and depression. The enormous, watchful monitors that follow nearly every private discussion and action are more terrifying than any bookburning scene in the movie. Our personal and public lives are becoming public information at a pace and to an extent few of us predicted even five years ago. When we interact with the Internet at home or at work, we accept increasingly high levels of personal intrusion.
