More generally

Library science (often termed library studies, bibliothecography, library economy, and informatics)[note 1] is an interdisciplinary or multidisciplinary field that applies the practices, perspectives, and tools of management, information technology, education, and other areas to libraries; the collection, organization, preservation, and dissemination of information resources; and the political economy of information. Martin Schrettinger, a Bavarian librarian, coined the discipline within his work (1808–1828) Versuch eines vollständigen Lehrbuchs der Bibliothek-Wissenschaft oder Anleitung zur vollkommenen Geschäftsführung eines Bibliothekars.[1] Rather than classifying information based on nature-oriented elements, as was previously done in his Bavarian library, Schrettinger organized books in alphabetical order.[2] The first American school for library science was founded by Melvil Dewey at Columbia University in 1887

The author's experiences as a master's and doctoral student at the University of California at Berkeley School of Library and Information Studies during a formative period in the history of information science, 1966-71, are described. The relationship between documentation and information science as experienced in that program is discussed, as well as the various influences, both social and intellectual, that shaped the author's understanding of information science at that time.
