Departmental libraries: why do they exist?

In response to an increasing concern on the part of the library staff over the role of the departmental libraries at The Milton S. Hershey Medical Center of The Pennsylvania State University, a questionnaire was developed by the George T. Harrel Library and sent to departmental libraries. From the analyzed responses, the authors were able to define the role of departmental libraries in a medical school/hospital situation, to analyze the Hershey Medical Center situation in an objective manner, to outline areas of possible cooperation between the main and departmental libraries, and to delineate some trends which appear to result from inadequate finding of a central library. Overall, the library found that departmental libraries at Hershey are currently maintaining collections consistent with the functional role of a departmental library.
