Library science, more accurately labeled "librarianship," is a professional area of study, it is not a science, even though most library schools incorporate information science in the curriculum. Graduates of library schools are primarily concerned with such tasks as evaluating, processing, storing, and retrieving information, and with collection development and bibliographic processes and products. Librarians a(e being called upon to learn audiovisual and computer technologies and applications. They also help library patrons to use the materials and equipment. The librarian is more concerned with the management of systems, the information scientist with the recreation. Information scientists analyze the many and various phenomena that affect any aspect of information. They are interested in determining such things as(1) the life cycle and utility of Literature on a given subject (bibliometrics), (2) patterns of authorship (co-citation analysis),and (3) the impact of reading on groups and societies (social epistemology).This work, in two volumes, gives vivid and authentic information of Library and information science with emphasis on teaching aspects of the subject.
