Library scienceÂ is anÂ interdisciplinaryÂ orÂ multidisciplinaryÂ field that applies the practices, perspectives, and tools of management, information technology,Â education, and other areas toÂ libraries; the collection, organization,Â preservation, and dissemination of information resources; and theÂ political economyÂ of information. The first American school for library science was founded byÂ Melvil DeweyÂ at Columbia University in 1887. Â The first textbook on the subject was German. Historically, library science has also includedÂ archival science. Â This includes how information resources are organized to serve the needs of select user groups, how people interact with classification systems and technology, how information is acquired, evaluated and applied by people in and outside of libraries as well as cross-culturally, how people are trained and educated for careers in libraries, theÂ ethicsÂ that guide library service and organization, the legal status of libraries and information resources, and the applied science ofÂ computer technologyÂ used indocumentationÂ andÂ records management. It is expected that the book will provide a fund of rich experiences to the students and teachers.
