VALIDATION RECORDS

    The Cataloging Policy and Support Office (CPSO) has begun
creating and distributing  subject authority records called
"validation records" that represent valid 6XX headings plus
subdivision strings (topical, chronological, geographic, and form),
including strings with free-floating subdivisions for which subject
authority records were not previously made.  Validation records are
being created to improve the "validation" capability of many
integrated library management systems used by the Library of
Congress and others by providing an authorized form of subject
heading strings for machine matching.

     The validation records are identified by the presence of the
667 field which reads: "Record generated for validation purposes."
All validation records will appear in LC's online catalogs but will
not be printed in the annual edition of _Library of Congress
Subject Headings_ nor will they appear as proposed headings on the
_LC Subject Headings Weekly List_.   As of Sept. 25, 2007, 1,900
validation records have been distributed.  Some examples are:

         sh2007005269 Abdominal wall$xAbnormalities   (May Subd
Geog)

         sh2007100421 United States$xEconomic policy$vPeriodicals

         sh2007100247  Great Britain$xRelations$zUnited States

         sh2007100224 Indians of North America$vSongs and music

    CPSO is creating the validation records by using a combination
of one-by-one record creation as subject strings are encountered in
weekly operations and use of an automated program to generate and
distribute validation records without human intervention.  For this
latter automated method, the focus is on subject heading strings
applied since the year 2002 for which the LC catalog contains fifty
or more bibliographic records that include the same 6XX string.
Once the automated program is tested and approved, several thousand
records are expected to be generated and distributed each week.
CPSO will make an announcement before the automated method is put
into full production.

    Questions regarding validation records may be sent to Ron
Goudreau, editor of subject headings, at<[log in to unmask]>.
