This encyclopaedia offers a comprehensive examination of how information technology is organised, managed, and applied within modern library and information science environments. It explains the transformation of libraries from print-centred institutions into digitally driven information systems, focusing on the organisation, retrieval, storage, and preservation of information in electronic formats. The book explores how automated systems support acquisitions, cataloguing, classification, and user access, while also addressing system design principles that underpin efficient digital library operations. Emphasis is placed on managing digital information lifecycles, including data curation, migration, long-term preservation, and sustainable access. By integrating technological frameworks with library management practices, the book provides a structured understanding of how information systems enhance decision-making, service delivery, and knowledge organisation in contemporary libraries.

The book also focuses on strategic and participatory dimensions of digital information management, examining collaborative digital repositories, metadata frameworks, and open architectures that support interoperability and access. It highlights challenges related to digital preservation and future-proofing information resources. Designed for students, librarians, information professionals, and researchers, the book serves as an authoritative reference on organising information technology and managing information science in library and digital knowledge environments.
