The Joint Steering Committee for Development of RDA has issued a document outlining the changes made to AACR2 as a result the RDA development process.
“This document lists changes made to AACR2 instructions during the development of RDA as noted at JSC meetings and in JSC correspondence.
This document does not cover RDA elements for which there is no equivalent in AACR2 (e.g., Production statement; Uniform Resource Locator), or AACR2 instructions that have been generalized in RDA to cover a wider range of resources.
The instruction numbering used corresponds to 5JSC/RDA/Full draft (November 2008). Where instructions differ from what is in the draft, a note such as “(Note: Instructions changed at March 2009 meeting)” has been provided.“
