To learn about the new OCLC guidelines for abbreviated-level (encoding-level 3) records.
All sections describe changes that may affect local system processing of OCLC-MARC records.
No system changes are needed to accommodate these guidelines. Catalogers may begin using these guidelines immediately for original cataloging at the abbreviated level.
Contact your OCLC regional service provider or the user training development manager at OCLC if you are an independent institution.

Throughout the technical bulletin, R = Repeatable and NR = Nonrepeatable.
OCLC implemented support for Encoding Level value 3 (abbreviated-level) several years ago but at that time there were no established standards for the content of an abbreviated-level record. In the intervening time, some individual institutions have laid out their own guidelines for use in particular projects and have expressed a desire to include those records in WorldCat.
OCLC staff have worked with the Collections and Technical Services Advisory Committee and the Members Council Cataloging and Metadata Services Group to establish OCLC-defined guidelines for the content of abbreviated-level records. The elements listed below have been chosen particularly to support accurate identification of materials for cataloging and discovery purposes and to support automated matching processes.
These guidelines may be used immediately for original cataloging at the abbreviated level. All fields not included in this list are Optional for abbreviated-level records.
