Abstract:  Definitions of authorized users in license agreements not only dictate who is allowed to access licensed resources, but also define who can be considered part of an institution’s user community. Researchers engage in collaborative research, sometimes holding multiple affiliations that, at times, may extend beyond a definition of authorized user. This paper examines how libraries play a role in supporting or inhibiting collaborative research by exploring a strategic partnership between the University of Colorado Boulder (CU Boulder) and the National Center for Atmospheric Research (NCAR) to further collaboration related to atmospheric research and climate studies. While the goals of the partnership sought to enhance research and collaboration through access to licensed resources, the authors found that the paywalled model of access through license agreements, authentication, and access and discovery methods has complicated the effectiveness of creating a collaborative research environment.
