Purpose: Data standardization and the harmonizing of procedures are essential to ensure the integrity of a shared bibliographic database. This document defines the bibliographic standards and procedures to be followed by all NYARC institutions contributing new bibliographic records to the NYARC Integrated Library System (heretofore referred to as Arcade). It is recognized that legacy data not conforming to these standards and policies exists in Arcade.
