1 Introduction

Background

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.
