Libraries Policies: Cataloging Policies
      Standards for Local Cataloging

Cataloging produced for inclusion in the local online catalog is performed in accordance with certain national and international standards:


Most of the collections are classified according to the most recent editions of the Library of Congress Classification System (LCC). Older materials that were originally classified using the Dewey Decimal Classification (DDC) retain their Dewey numbers until some circumstance triggers a reclassification. Government Documents are assigned Superintendent of Documents (SuDocs) and other document numbers as appropriate. Exceptions to the general policy for classification in LCC may be made for certain groups of materials for which actual subject classification is impractical or for which association with the particular group is considered critical. Such materials may receive group or accession-based call numbers rather than a classification number.  For a full list of approved exceptions, see Classification-approved Exceptions to Standard Practice.


Materials are described according to the most recent version of the Anglo-American Cataloguing Rules, second edition (AACR2). In the case of certain materials, AACR2 may be augmented but not replaced by use of an authorized "manual of interpretation". The term "manual of interpretation" is used to denote any of the authoritative extensions or interpretations of AACR2 for particular types of materials, such as Descriptive Cataloging of Rare Books; Henson's Archives, Personal Papers, and Manuscripts; Archival Moving Image Materials; Graphic Materials; Guidelines for Description of Interactive Multimedia.


Subject Headings
Materials are assigned subject headings from the current version of the Library of Congress Subject Headings (LCSH). When pre-existing bibliographic copy contains MeSH or LC Juvenile Subject Headings, these headings are retained on the copy.


Content Designation
Records are tagged and coded for machine manipulation according to the current version of the OCLC/MARC formats, as augmented and/or revised by local system documentation.


Exceptions to these practices are made only for compelling reasons, and only after due consideration and consultation with those affected. For materials cataloged by units outside Technical Services, this includes consultation with Technical Services.
