Understanding the nature and complementarity of the phenomena of information and knowledge lend not only epistemological clarity to their relationship, but also reaffirms the place of the library in the academic mission of knowledge transfer, acquisition, interpretation, and creation. These in turn reassert the legitimacy of the academic library as necessary participant in the teaching enterprise of colleges and universities. Such legitimacy induces an obligation to teach, and that obligation needs to be explored and implemented with adequate vigor and reach. Librarians and the academy must, however, concede that the scope of the task calls for a solution that goes beyond shared responsibilities. Academic libraries should assume a full teaching function even as they continue their exploration and design of activities and programs aimed at reinforcing information literacy in the various disciplines on campus. All must concede that need for collaboration cannot provide grounds for questioning the desirability of autonomous teaching status for the academic library in information literacy educatio
