Through this program, participants contribute authority records for agents, places, works, and expressions to the LC/NACO Authority File. Membership in NACO is open to individual institutions willing to support their staff through a process of training, review, and direct contributions of records to the LC/NACO Name Authority File.
Please note: Library of Congress fiscal 2023 appropriations will expire on September 30, 2023. If appropriations for fiscal 2024 are not enacted by this date, the Library will be closed. Until the Library reopens, meetings will be canceled and rescheduled for a later date. Email accounts and discussion lists ending in "loc.gov" (coop, policy, pccd, naco, etc.) will not be monitored. LC has taken steps to ensure that staff who process NACO contribution/distribution will be available in case there are problems, so NACO processes can continue without interruption. Classification Web Plus and the PCC Directory will continue to function, but no support services will be available. For updates, please monitor the news or call the Library of Congress information line at (202) 707-5000.

This training is currently offered sequentially in segments that amount to a five day workshop. During the training, guidelines are discussed and expanded upon with an emphasis on building a consistent and predictable file in a collaborative environment.

NACO Advisory Group
- More about the NACO Advisory Group
The NACO Advisory Group is a PCC group that monitors PCC listserv discussion of NACO-related topics, and provides input when a NACO-related topic appears to be unresolved, unanswered, or ambiguously answered, in routine PCC listserv discussion. The advisory group may refer to existing NACO documentation, refer to a NACO best practice, or indicate that the topic may need additional investigation and policy discussion.
