For several years, academic institutions have been establishing and maintaining institutional repositories (IRs) to collect, make accessible, preserve and showcase the institution’s research and scholarly output. At a majority of institutions, the library is the entity that takes on the responsibility of organizing and maintaining the repository. As the nature and purpose of IRs has evolved over time, the opportunities and challenges for units within the library have also shifted. What has been the impact of IRs on academic libraries and specifically, on technical services functions within the library? What are some of the contributions technical services units can make to insure the success of an IR? This talk will address these questions and explore the changes in professional roles, resources and organizational structures that are currently taking place in academic libraries to support IR programs.
