This classic textbook provides a broad overview of the systems and practices that contribute to service delivery in digital and hybrid library and information services. Since the publication of the last edition, society in general - and library and information services in particular - has experienced significant IT-driven evolution and change. This new edition has been completely overhauled to reflect these changes and to develop key themes, including: information retrieval via the internet; document and content management systems; digital archiving and preservation; and management of electronic resources, including the expanded role of the Library Management System. To facilitate learning, this established text is structured to include: learning outcomes, reflections, summaries, review questions, case studies, references and a full bibliography. It is an essential student purchase and a valuable source of professional updating for all practising library and information professionals.
