1. INTRODUCTION
In modem societies, every human activity is organized through institutions. Every major social task, whether economic performance or health care, education or research, business or industry is institutionalized. The protection of the environment or defence is today invariably entrusted to institutions and organizations. Libraries and other similar types of institutions are those that collect, stock, process, organize, disseminate and distribute information/knowledge recorded in documents. Since knowledge and information are so vital for all round human development, libraries and other institutions that handle and manage knowledge and information are indeed invaluable. In this Unit, you are introduced to the important role that libraries play in the educational process of formal and non-formal learning, in research and development, in cultural activities, in spiritual and ideological realms, in recreation and entertainment, etc. With spectacular advances in information technologies and increasing categories of users and their information needs in different situations, modern society is heading towards an information society in which the central instrument of change, force and direction of change are knowledge and information. All these ideas are discussed at some length in this Unit. Assimilation of these ideas is essential for you to get a full appreciation of the role of libraries. This will enable you to develop a proper insight into professional practice and performance. In the succeeding sections of this Unit, we shall discuss how the library plays its role.
