The release of Resource Description and Access is not the release of a revised standard; it represents a total shift in the understanding of the whole cataloguing process. This shift from the Anglo-American Cataloguing Rules (AACR) to RDA will require a fundamental re-orientation in the way library staff, especially cataloguing staff, approach the function of describing resources and creating access to them. This book will assist professionals with this transition. The book guides the reader through the key topics and questions providing a concise explanation of RDA, its implementation and its expected benefits for users and cataloguers. Key sections include: - what is RDA? placing RDA in context - why are we changing to RDA? - making the transition to RDA - after implementation. Readership: This book is an essential introductory guide not only for cataloguers but for all library staff, information professionals, support staff and LIS students
