Although the literature of library administration draws extensively on that of business management, it is difficult to compare library supervision to business or industrial supervision. Library supervisors often do not have managerial training and may consider their management role as secondary. The educational level of the staff they supervise may be higher than those in business, and the financial structure of the library prevents the use of standard industrial personnel practices such as bonuses. The supervisor must have knowledge of the tasks to be performed by the person to be supervised and of the fundamental concepts of management, including organization theory, leadership theory, and the techniques of motivation. Although not all professionals who work for libraries supervise, the schools of library and information science should consider including supervisory training in their programs. Supervision is an aspect of professional work which requires more consideration than it has had to date; the human relations aspects of library work are in need of attention. (Author/SL)
