As many of you are aware, the Library of Congress has started the
distribution of the authority records associated with RDA, Phase 2.
   This phase includes the distribution of approximately 400,000 name
authority records that are candidates for change.  As with the Phase 1
change completed in the summer of 2012 (see
http://www.loc.gov/cds/notices/120717.pdf
<http://www.loc.gov/cds/notices/120717.pdf> ), the records will be
adjusted in the LC database and distributed to the NACO nodes and other
CDS customers.  LC is updating and distributing 30,000 records per day,
Monday thru Friday, until the changes are completed (the final day of
changes distributed may be less than 30,000).  These updated records are
in addition to the regular distribution of LC/NACO transactions.

The distributed files will continue to load at OCLC the day following
their distribution, resulting in Tuesday thru Saturday.

Linked headings in bibliographic records are updated as the records are
loaded, and a single authority record can be associated with hundreds of
occurrences in bibliographic records.

As a result of the increased volume, the ability to immediately apply
updates to linked headings in other bibliographic records when an
authority record is modified in Connexion will be delayed.

Please do not send reports for headings that were not immediately
updated until the completion of this project.
