The result of the US national libraries test has now been released. Information on the test is available at: www.loc.gov/bibliographic-future/rda/. The US national libraries have agreed to implement RDA no sooner than January 2013 so that the issues identified during the test can be addressed.
The non-US national libraries involved in the development of RDA (Library and Archives Canada, the British Library and the National Library of Australia) will review the reports and consider the implications for the scheduling of their implementation of RDA. Further information will be posted as it becomes available.
