Procedural Guidelines for Proposed New or Revised Romanization Tables
News from LC.
I am pleased to report that the "Procedural Guidelines for Proposed New or Revised Romanization Tables" is now available on the LC website at http://www.loc.gov/catdir/cpso/romguid_2010.html. These guidelines were developed jointly by the Policy and Standards Division at the Library of Congress, the Committee on Cataloging: Description and Access (CC:DA) and the Committee on Cataloging: Asian and African Materials (CC:AAM) within the Cataloging and Classification Section of the American Library Association. The need for a formal procedure became apparent in recent efforts to revise certain Romanization tables. A draft was issued on June 15, 2010, with a request for feedback. The current procedure, dated August 13, 2010, is the result of that feedback and was printed in Cataloging Service Bulletin Issue 127http://www.loc.gov/cds/PDFdownloads/csb/CSB_127.pdf (PDF, 289 KB).
