To promote more effective use of the library by the undergraduates at the University of Colorado, Boulder, a program was implemented within the departments of history and economics to improve liaison between faculty and library personnel. Two subject librarians were appointed who would work half-time in their respective undergraduate departments and half-time in the reference department of Norlin Library, the undergraduate humanities and social science library. The duties of the special librarians would include group and individual instruction of students in library skills and subject area bibliography, the preparation of instructional aids in the literature of history or economics and in library use, and the establishment of closer liaison with the department faculty. Within the economics department, during the 1973-74 school year, there was a high level of activity, including many hours of student contact and faculty cooperation in implementing a library instruction plan in the various courses offered by the department. Student attitudes were tested by a questionnaire administered before and after the program. A proposal has been submitted for an ongoing formative evaluation of this project. (SL)
