This article prepares catalogers for the new cataloging standard Resource Description and Access (RDA) by giving trainers and Library and Information Science (LIS) educators the information they need to plan training for themselves and their staff or students. The theoretical principles of RDA are introduced as well as the corresponding vocabulary that trainers will need to use. This is followed by an overview of the structure of RDA as compared to the Anglo-American Cataloguing Rules (AACR2). Examples of rule changes and options are highlighted for trainers along with a reminder to review existing cheat-sheets and manuals that are based on AACR2.Finally, types of training formats are suggested.
