A Subject Librarian and an Institutional Repository (IR) Librarian will discuss new strategies for working collaboratively to build the IR and promote its use. At USU, subject librarians not only market the IR to their departments, but also clear copyright for scholarly works to be included in the IR. This new model helps USU build the IR more quickly, and it helps subject librarians learn about their subject areas while building relationships with their constituents. This new model, though, also presents new challenges. Attempts to overcome these will be discussed.
