Description

In the strictest technical definition, Information is a series of symbols that can be read as a message. Signals or signs can be used to send or record information. Any event that changes the state of a dynamic system is considered to be information. Information is conceptually the message being delivered. Numerous more interpretations of this idea exist in other contexts. The idea of information is also intimately related to the ideas of restriction, communication, control, data, form, instruction, knowledge, meaning, mental stimulus, pattern, perception, representation, and particularly entropy. In order to research topics relating to libraries, the collecting, organisation, preservation, and transmission of information resources, as well as the political economics of information, library science is an interdisciplinary field that combines the humanities, law, and applied science. Encyclopaedias, periodicals, and more recently, electronic media, are just a few of the many sources of current information that academics, students, and faculty actively seek out from libraries. The way library patrons seek out information has changed dramatically in this "E" era. All persons with an interest in the fields of library science are expected to find the book's contents valuable.
