Authority control
Authority control in a library environment is the establishment and maintenance of consistent forms of names and terms to be used as authorized access points in records of the library catalog. Authorized access points must not only be consistent, each one must be unique. Traditional library practice focused on controlling names (personal, corporate, governmental, and geographic), works, and subjects. While authority control has always been important for library catalogs, with the growth of new environments of linked data it is becoming even more so, with increasing elements in the catalog being represented by authorized forms. (One example: using authorized terms for occupations in authority records.)
See Contacting people for authority control for details on contacting authority file subjects directly.
Authority control at the Folger
The Folger is a member of NACO and SACO; the PCC liaison is Deborah J. Leslie. For NACO training schedule and workflows, see NACO in Bard2. (Access limited to Folger staff).
Policy
- Create authority records for unestablished name access points used in bibliographic records, with the exception of former owners.
- All data elements must be justified in the NAR itself, with a source in the 670 (or, rarely, in a $v in the case of a 3XX that for some reason isn't practical to justify in a 670). Information may be inferred.
- Routinely add 046, regardless of how specific the available information is and whether it's used in the AAP.
Special cases

Booktrade
See the talk page for ongoing discussion on choice of terms and term clusters. Printers, etc. should be established and traced as individuals or corporate bodies based on how they are represented in imprints. In case of doubt, establish a personal name access point when a verb is used in connection with the name, and a corporate body when a noun is used. If both are used interchangeably during the same time period, establish and trace as a corporate body.
Personal names
In general, do not get any more specific than "Book industries and trade" for field of activity for a person.

Corporate names
For the field of activity of a firm, use both the broad "book industries and trade" as well as the more specific industry.

Workflow
For more detailed workflow during training, see NACO workflow in Bard2. (Access limited to Folger staff)
New NARs from current cataloging
- Cataloger searches the NAF thoroughly.
- Cataloger searches the local shared save file.
- Cataloger creates NARs in the local shared authority save file with workflow status In process.
- When NAR is ready for review, the cataloger changes the workflow status to In Review.
- Upon review, the reviewer changes workflow status to Complete if the NAR is ready to be added to the NAF, or back to In Process if any revision or discussion is needed. For completed NARs, go to step 6.
- When the NAR is ready for additional review, cataloger changes status to In Review. Repeat steps 3-4 until the NAR is marked Complete.
- Cataloger re-searches the NAF, and if no conflict has arisen in the meantime, adds the NAR: keystroke = Ctrl-Alt-A || menu = Action - Add to Authority File.
- Cataloger exports newly-contributed NAR to Voyager: keystroke = F5.
- Cataloger searches briefly to see whether BFM is needed by LC; if so, reports to NACO liaison. (See Guidelines for Reporting BFM)
- Cataloger deletes NAR from save file.
New NARs from retrospective projects
- Cataloger searches Hamnet to make sure the authorized access point is used on a bibliographic record. If not, delete the saved NAR.
- Follow steps 2-9 for NARs from current cataloging.
- For 19th- and early 20th-century books, it may be worth searching for a digitized copy; there may be additional information about the person on the title page or another prominent source not recorded by the creator of the original NAR. (Five-minute rule.)
- Cataloger updates access points in Voyager bibliographic records if different from the newly-established form.
- Cataloger updates access points in Connexion master and institutional bibliographic records if different from the newly-established form.
