Therefore, information science is the field of study concerned with all phases of knowledge communication, the information transfer process, and the investigation of the needs of information systems' users. Historically, information science dates back to roots around 669-630 B.C., and the cuneiforms in Ninevah. A strict view of information science can be seen as the intersection of the following fields. Information Theory - cybernetics, linguistics, formal logic, systems science . Information Technology - hypertext, electrical engineering, computer programming.
Information specialists deal with the organization, storage, and retrieval of information.
They also may be involved with abstracting and indexing, systems analysis, computer programming, cataloging, and classifying. Because the transfer, storage, and retrieval of information relies largely on computer systems, information science is closely tied to computer science . For example, authorities who determine environmental regulations need accurate, relevant environmental information from which to base their decisions. This relation, between information science and environmental informatics, has lead to the development of several on-line global networks. Commercial on-line services are also available.
