If David Weinberger is to be believed, the Internet hasn’t just changed how we access information, it has altered the very meaning of ‘knowledge’. In a recent interview with The Atlantic, Weinberger claims that “for the coming generation, knowing looks less like capturing truths in books than engaging in never-settled networks of discussion and argument.” Supposedly, the networked, collaborative, and social nature of the Internet has changed our very understanding of knowledge to the point that knowledge is no longer tied to concepts of truth, objectivity, or certainty. Instead, as Weinberger argues in his recent book, Too Big to Know, “knowledge is a property of the network” (p. xiii). That is, the Internet has profoundly changed what it means to be a fact, to be true, or to be known. This book has been making the rounds among librarians, so I thought it might be a good idea to try to explain Weinberger’s argument and what librarians should–and should not–take away from it.
