The Metropolitan Library Service Agency (MELSA) of Minneapolis/St. Paul was formed through an agreement among local library districts to share collections, services, and loans. During the formative years of the program, state aid for regional library development was apportioned to local branches on a per capita basis. Since this method did not reflect actual use patterns, a study was initiated to ascertain the portion of each library's budget spent on interlibrary sharing and to measure use of each library's facilities by the other libraries. Tabular results of the survey are provided. (EMH)
