Purpose: promote consistency in recording serial holdings by following the national standards.
Yale generally follows Level 4 (detailed holdings) of the current national standard for recording serial holdings: ANSI/NISO Z39.71-1999. Holdings Statements for Bibliographic Items. (Yale deviates from the current standard when recording some serial recon holdings.) The current standard supersedes: ANSI Z39.44-1986. Serial Holdings Statements.
Yale uses the MARC 21 Format for Holdings Data to store serial holdings records in machine readable form. At this time, Yale uses the MARC fields for textual holdings: 866, 867, 868. The MARC 21 standard supersedes: USMARC Format for Holdings Data, 1989.
