We are better prepared today to deal with the problems in library administration, because we not only have the basic work of management theorists, but also staffs who are better educated and more interested in participation. During the last 25 years, there have been two strands in library administration. The older, human relations approach allowed individuals to work in productive cooperation. The scientific approach of the fifties and sixties, on the other hand, emphasized rigid measurement, machines, and statistics. However, the latter approach came to libraries at a time when the management field in general was moving back to the humanistic methods of Douglas McGregor and the motivational psychologists. The newer theories make a major contribution to library administration and provide a framework for considering the complexity of forces which are having an impact on administration of all kinds; the thrust toward greater democratization and the historical tendency of Americans to want strong, even authoritarian, managers. The magic of administration comes in reconciling these contradictory trends through a careful analysis of the needs of one's institution and the leadership styles appropriate to meet them. (Author/SL)
