A variety of resources is needed to effectively carry out a comprehensive evaluation of any reasonably complex program of library instruction. At the State University College at Oswego, New York, the means and motivation for carrying out formal evaluation of a college library's instruction program were greatly enhanced when librarians cooperated with a campus research course. The library's program became a class project; faculty and staff shared their expertise; and these symbiotic efforts resulted in a fairly comprehensive evaluation project. The total evaluation process has included a faculty needs assessment, evaluation of current library instruction offered through freshman English and upper-level psychology courses, and feedback from graduating students. The research results have prompted improvements in the library instruction program, and they form a basis for continuing evaluation. This case study suggests that librarians look to their campus environments for stimulus and help, since colleges are usually rich in resources needed for program evaluation. (Author/KM)
