Historically, attention to grey literature in the academic library was focused on external collections – documents produced by government agencies or research centers. Little, if any, systematic attention was paid to the grey literature that was produced on university campuses. The advent of the Web, while bringing more interest to grey literature in general did not change this situation much. However, the trend toward the creation of institutional repositories has caused a considerable shift in interest. The formalization of collecting, processing, and integrating academic institutional grey literature should be critical to the mission of the University, regardless of format, and regardless of the existence of an active institutional repository. This chapter reviews a study on academic grey literature from earlier in the decade and provides an updated perspective.
