Foundations of Library and Information Science starts with a conversation of the practice of librarianship, and shifts on to tackle the place of libraries within the broader point of view of the information superstructure, the development of information science, the expansion of information technologies, information policy in libraries, intellectual organization of libraries, the mission of libraries from past to present, and ethical aspects and principles between information providers and clients. The several types of libraries, their internal functions, and the major organizational issues they face are discussed.
