Often invisible to the broader society, the information disciplines determine much of what is available to these societies from their entire heritage of knowledge, culture, and entertainment. Containing the contributions of major researchers and practitioners, this third edition of the "Encyclopedia of Library and Information Sciences" reflects the growing convergence among the several disciplines that concern themselves with information and the cultural record. This work addresses these related disciplines in a way that demonstrates the unities across the fields and also recognizes their uniquely distinguishing characteristics. It covers a broad spectrum of related information disciplines, including: archival science; bibliography; document and genre theory; informatics; information systems; knowledge management; library and information science; museum studies; records management; and, social studies of information.
