The only workbook created for the new RDA, this resource is an important tool that will help readers at any level of experience develop and strengthen their understanding of RDA content and structure. With the extensive changes to RDA and the RDA Toolkit brought about by the 3R Project, the need for a truly practical tool for learning RDA has never been more acute. Designed to be used by practitioners, training staff, and in the classroom or by students individually, this workbook offers a self-paced way to become familiar with the new RDA Toolkit. Current with RDA instructions through the September 2020 update to RDA and MARC 21 updates through May 2020, it serves as a bridge between theoretical concepts and hands-on cataloging. James, whose experience includes former cataloging policy specialist at the Library of Congress, former member of the RDA Steering Committee, former RDA Examples Editor, and former member of the RDA 3R Core Team, covers all 13 entities as well as the Toolkit's organization and interface. Included are a variety of MARC and non-MARC exercises designed to give practical experience using the new RDA Toolkit, with application profile assumptions that mimic a real cataloging environment.
