Introduction
The Public Services Department is one of the professional departments of the National Library of Nigeria. Section (2) {b) of the National Library decree 1970 provides for the establishment and maintenance of a branch of the National Library in each of the states of the federation. This requirement was designed to bring library services closer to the people. In pursuance of the State Branch Services objectives, presently, there are thirty-three {33) established operational branches located all over the six (6} geo-political zones of the country. The State Branch system is organized into two Divisions: Public Services Department Southern Operations Division and Northern Operations Division. These two divisions have operational units under them for the coordination of the activities of the department.
The department came to being as a result of the merger of State Branch Services and Reference and Users Services Department. Since then, the state branch system has undergone two other significant changes. First, was the splitting up of the department into two (2} departments: The Public Services Department (PSD South} and the Public Services Department (PSD North} - each of the department headed by a Director to oversees, co-ordinates, set targets for annual performance, plan specific projects and supervises the state branches' functional operations. Second was the subsequent merger of the two departments as one but with creation of more divisions and units.
