Queries to the Library of Congress (Additions and Changes to Authority Records)

The same basic procedure for queries regarding new authority records is used for queries on updated authority records.

1. Reporting Bibliographic File Maintenance (BFM):

When a change in an existing authority record results in necessary changes to headings in LC bibliographic records, NACO participants must notify Coop Cat. The NACO Coordinator may combine queries about new records and updated records in one e-mail message to Coop Cat.

2. Other Queries:

NACO participants are asked to research problems as fully as possible before referring them to Coop Cat. Queries may include:

a. NLC -- asking Coop Cat to verify a Canadian heading with the National Library of Canada.

b. NLM -- asking Coop Cat to verify a heading with the National Library of Medicine.

(Both NLC and NLM are considered to be equivalents to LC, and permission must begranted before their headings are changed.)

c. Request for Coop Cat to check changes to an authority record for errors. After independent status is granted, NACO participants may to ask Coop Cat to check individual headings when necessary.

d. Request for assignment of a literature class number (053).

e. Questions about series authority records or other NARs, such as music uniform titles, that are not within scope for many NACO libraries.
