At the ALA Annual Conference in New Orleans in June, the members of the RDA Steering Committee and friends organized a day-long event called "A Practical Introduction to the New RDA Toolkit". If you missed the event, you can still learn a thing or two about the new RDA Toolkit through slides and video from the event, all linked below.
NOTE: The beta site is a work in progress and is not yet approved by the RDA Steering Committee for use in cataloging.
Slides of the presentations can be found here.
Videos of presentations are here.
