The underlying principle of NACO is that participants agree to follow a common set of standards and guidelines when creating or changing authority records in order to maintain the integrity of a large shared authority file. During the week of NACO training these guidelines are discussed and built upon with a view to streamlining processes while building a consistent and predictable file that will reduce the duplication of efforts of the global library community and maximize its resources.
