This article, “Faculty Attitudes Toward Collaboration with Librarians,” by Dr. Atif Yousef looks pretty good.
From the introduction:
University libraries play a vital role in supporting their parent institutions to achieve their objectives effectively. Librarians and faculty members are both involved in teaching students how to make use of the information resources available in their campus library. Collaboration between faculty and librarians is essential to enhance students learning and research, and help them develop their information competencies.
