 Colleges and universities in the United States have often published official or unofficial books listing their students, faculty, or staff, together with pictures and limited biographical data.By the early 2000s, some face books were being published online offering a number of new features, including password protection, more detailed information, more advanced indexing and searching, and the ability for people to upload and enter information and photographs.In early 2004, Mark Zuckerberg, a sophomore at Harvard University, created an unofficial online face book at the website "thefacebook.com", the forerunner of the Facebook service, out of frustration that the university's official online face book project was taking too long.
