OCLC RDA Policy Statement
"OCLC member libraries may contribute new unique records to WorldCat formulated according to any cataloging code they are currently using. OCLC will not require libraries to use RDA. Libraries may switch to RDA for original cataloging on their own timetable, if they chose to switch at all. Libraries may continue to contribute records to WorldCat formulated according to AACR2 if they wish to do so." RDA takes effect on March 31, 2013.
