Students who are not urged to "touch books" often don't realize how much information is not on the Internet. According to Block, only about 15 percent of all information -- books, periodicals, government documents -- is found there. The full texts of articles from most academic journals, for example, are not online nor are most current books. Because of copyright laws, a lot of information may never make it to the Net, Block says, which is why she and other librarians worry about lawmakers who slash library budgets or propose eliminating libraries altogether, saying, "Why do we need them? Everything's on the Internet."
