Also worryingly, the Berkeley university Web Privacy Census (which aims to measure online privacy by conducting periodic web crawls and comparing the number of cookies and other types of tracking technology found over time on the most visited sites.) found the number of trackers collecting data on users’ activities on the most popular Web sites in the United States had significantly increased in the last five months  The main site also has very good literature reviews of internet privacy literature.
Other good starting points are the Electronic Frontier Foundation.
