Subject Authority Records

News from LC.
CPSO has begun a project to create subject authority records for every subject string appearing in bibliographic records to aid Library of Congress catalogers, and external users in the validation of LCSH subject heading strings. Effective immediately subject authority records are being created for valid subject strings obtained from bibliographic records. Formerly, these subject strings did not prompt the creation of subject authority records, because they contained free-floating subdivision[s].

Some of these records are being created manually by the Cataloging Policy and Support Office staff, and some will be generated by machine, but all of them will be reviewed before distribution occurs. We anticipate at least 200 records per month at the start of this project. These records will not be printed in the annual editions of LCSH (the "red books"). The records can be identified by the legend "[proposed validation record]" appearing at the end of the 1xx string. This legend will be removed once the records have been approved and distributed. Additionally each record will contain a 667 field with this data: "Record generated for validation purposes."
