This paper will explore the social epistemology of the Web 2.0 and how its tools can help librarians not only foster information literacy in young users, but motivate them to use library services and programming. This article will first briefly discuss both Shera and Goldman’s views on social epistemology, and the relation of social epistemology to library and information science. Second I will include a brief history and definition of Web 2.0 and Library 2.0 focusing on a few of its tools such as social tagging and folksonomies, and then move on to the influence these tools have on the way young people learn. This paper will explore how to use the tools of web 2.0 in a library setting to foster the research and organizational skills, and explain how these tools can motivate young users to enter the library and better utilize library services.
