Library science 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. The first American school for library science was founded by Melvil Dewey at Columbia University in 1887.  The first textbook on the subject was German. Historically, library science has also included archival science.  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, the ethics that guide library service and organization, the legal status of libraries and information resources, and the applied science of computer technology used indocumentation and records management. It is expected that the book will provide a fund of rich experiences to the students and teachers.
