Professional librarians working in public libraries are generally evaluated in a number of ways, including standardized forms. By collecting and studying these forms, it was proposed that certain management traits and behaviors could be identified and compared. A total of 115 libraries serving municipalities with populations of more than 50,000 were identified. Each was asked to provide copies of blank standardized evaluation forms, along with basic information about the library and its process of evaluation. Forty-four library directors returned the survey, some evaluations, or both; and 40 supplied only the evaluation forms, a response rate of 35 percent. A large majority used standardized evaluation forms. Most evaluations were annual, and most were performed by the immediate supervisor. The size of the library was not reflected in these statistics. Analyzing the forms identified the following seven basic management skills: (1) planning; (2) organizing; (3) staffing; (4) directing; (5) coordinating; (6) reporting; and (7) budgeting. Not all management skills were evaluated at all libraries, and the diversity makes it impossible to determine if library administrators are consistently concerned with the management skills of their staffs. Two tables list the skills identified and the types of questions on evaluation forms. Five appendixes contain the survey and other letters used to conduct the survey. (Contains 26 references.) (SLD)
