This Review describes ways to examine various aspects of community college libraries. Little research has been done on the reasons for success or failure of certain procedures or of certain administrative or organizational forms. The criteria most often used for successful library service in the junior college (size of collection, size of staff, space, circulation figures) are called "process" criteria, and their use is analogous to judging an instructional program by the number of advance degrees held by the faculty. "Product" or "outcome" criteria might be better used to assess the library's contribution to the total instruction program. When they are determined, they will make the measure of success a challenge. (HH)
