The final chapter includes ten records displayed in AACR2 level 1, AACR2 level 2, RDA and MARC 21, making it easy to see the differences at a glance. There is also a fully explained worked example based on RDA Appendix M. Readership: Written at a time of transition in international cataloguing, this book provides cataloguers and students with a background in general cataloguing principles, the current code (AACR2) and format (MARC 21) and the new standard (RDA). The contextual chapters provide library managers with an up-to-date overview of the development of RDA in order to equip them to make the transition.
