Library of Congress Pinyin Conversion Project

On Oct. 1, 2000, Pinyin became the standard system to be used by American libraries for the romanization of Chinese ideographs and the Chinese language.

Up to that date, the Wade-Giles system for romanizing Chinese texts (named for Sir Thomas Francis Wade who developed the system in 1859 and for Herbert A. Giles who modified it in 1912) had been used in libraries throughout the United States for a century.  The Pinyin system, however, was made the official system of romanization within the People's Republic of China in 1979 and had come to be widely used in ensuing years throughout the international community as well as by the United States Government, the news media and publishers. In order to adapt to these practices, the Library of Congress, which sets the basic standards for library cataloguing within the United States, set a date of Oct. 1, 2000 as the starting point for the official usage of Pinyin in library cataloguing records. From that date forward Pinyin would become the standard romanization system and the usage of the Wade-Giles system would be discontinued.

While it is relatively simple to start cataloguing new items using the Pinyin system, it will take some time before all older cataloguing records are converted from Wade-Giles to Pinyin. Currently, a retrospective conversion project is being undertaken by the Library of Congress, OCLC (Online Computer Library Center, Inc.) and RLG (Research Library Group--the corporate body behind RLIN (Research Library Information Network)).  For updates on the conversion project, please visit the Library of Congress Pinyin Conversion Web site at: http://lcweb.loc.gov/catdir/pinyin/pinyin.html

The Portland State Library will begin the conversion process sometime after migrating from the Sirsi OPAC system to the III OPAC system which is sceduled for the summer of 2002. For the present time you should continue to use the Wade-Giles and the Pinyin systems when searching the Portland State catalog.
