Adding or Editing Information in an Existing Field
Non‑MARC records have two types of fields:
•
Authority Fields. These include the author, subject, and series fields of a bib record. Records generally contain one or more authority fields. The authority record supplies information for authority fields in a bib record. Authority headings need to remain consistent across records. Before adding an authority, you need to use staff searching to see if the authority already exists in your database. If it exists, attach it to the record.
•
Nonauthority Fields. These include all of the fields of an authority record and the fields other than the author, subject, and series fields on bib records. If you have used staff searching and need to create a new authority record, you must fill all the fields on the authority workform. You add information directly into these fields.
