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.

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.
