One of the major issues in the management of academic libraries is the dual nature of staffing: the professional and the paraprofessional. Using the Academic Affairs Library of the University of North Carolina at Chapel Hill as a case study, this project investigates whether professional and paraprofessional staff in large academic libraries experience significantly different levels and sources of job satisfaction. Over 140 library employees were administered a modified version of Paul Spector's Job Satisfaction Survey (JSS), a standard instrument used to measure job satisfaction of employees in non-profit and human services organizations. While both types of staff were basically satisfied with their jobs, there were significant differences in levels of satisfaction in several areas. Professionals were significantly more satisfied than paraprofessionals in the areas of enjoyment of the work itself, coworkers, appreciation and recognition, promotion, pay, and overall satisfaction. Reasons for these differences are suggested as well as possible means to bridge the gaps between the two groups. The Questionnaire Packet is appended. (Contains 14 references.) (Author/AEF)
