The RDA Series Training Task Group, part of the PCC Standing Committee on Training, has developed and made available online its RDA NACO Series Bridge training materials. The bridge training is intended for NACO catalogers who are already independent in series authority work and want to make the transition to RDA series authority work. The eight-module series includes slides, videos, scripts, quizzes and a handbook. Among the topics covered are Identifying Series, Recording the Attributes of Series, Constructing the Series Authorized Access Point, and a comparison of series treatment in AACR2 and in RDA. An email account has been established to take questions about RDA series work: firstname.lastname@example.org. NACO catalogers who undergo the bridge training must work with a reviewer to achieve independent status before contributing RDA NACO series authority records to the national authority file.
