Written by an authoritative practitioner, this book explores the changing nature of cataloguing in the aftermath of e-journal invasion. It traces the development of the issue by examining changes in AACR2 and CONSER rules, focusing on the revision of AACR2, Chapter 12, and emergence of the concept of 'Continuing Resources'. The book analyzes challenges of e-journal cataloguing that stem from an ever-growing number of online publications and aggregator databases. It assesses the complexities of incorporating commercially produced cataloguing into a local database, and offers practical solutions to the most common questions in the process. The book concludes with a look into the future of e-resource cataloguing from technical and conceptual standpoints.
