The US National Test Partners were announced June 4.
For the complete list, visit the RDA Test Site at: http://www.loc.gov/bibliographic-future/rda/test-partners.html.
From my understanding, these institutions were chosen out of some 90 that sent in an application, and, were picked to represent various types of libraries and integrated library systems.
The RDA Test sites writes:
After some unforeseen delays, we have the pleasure of announcing the 26 partners that the US National Libraries RDA Test Steering Committee has selected to participate formally in our planned test of the content and online functionality of Resource Description and Access. Interest in participating in the test was far greater than we had anticipated. The Steering Committee devoted twelve hours, in two sessions, to reviewing more than 90 applications. Since there were so many excellent applications, ALA Publishing agreed to increase the number of temporary licenses to RDA Online that could be permitted during the test period. The Steering Committee’s goal was to be as inclusive as possible in terms of size and type of cataloging units, formats to be cataloged, and systems and rules used in the test. The final selections include representatives of all types and sizes of libraries–national, government, academic, public, school, special; archives; museums; book vendors; systems developers; library schools; and consortia and funnels. We also had to ensure that the test covered a very wide range of cataloging systems, OPACs, communication formats/schemas, and types of materials/resources cataloged. To be sure that the test would compare RDA to the full range of cataloging rules that are currently in use in the U.S., we selected partners that use AACR2, AMIM (Archival Moving Image Materials), DACS (Describing Archives: A Content Standard), CDP (Collaborative Digitization Project), APPM (Archives, Personal Papers, and Manuscripts), CDWA (Categories for the Description of Works of Art), DCRM (Descriptive Cataloging of Rare Materials), GIHC (Graphic Materials: Rules for Describing and Historical Collections), and CCO (Cataloging Cultural Objects).
It will be interesting to hear back from these institutions about RDA.
