Choose as the identifier for a person the name by which he or she is commonly known in the language and script of the catalog. If the person creates works that do not carry identifying text, such as paintings, determine the name by which he or she is commonly known from reference sources issued in the language and script of the catalog. If a person is commonly known by more than one distinct name, determine the name by which he or she is commonly known from reference sources issued in the language and script of the catalog or use the form of name that appears most often in published works in the language and script of the catalog. If a person has never used a name in the language and script of the catalog, choose as the identifier the name by which a person is commonly known in his or her published works in his or her language, or use the name as it appears in reference sources issued in his or her language or country of residence or activity.
If a person has changed his or her name, choose the latest name or form of name.
If a person writes under several pseudonyms, choose one to identify the person, using the principles above. Ensure that the catalog will allow a person interested only in the works written under one particular pseudonym to see only those works on request, matching on the transcribed statement of responsibility for the work that appears in each expression record (see 2.2.2).
If two different people have the same name, add birth and/or death dates, initials, middle names, or any other biographical information that will serve to identify each person unambiguously and distinguish them from each other.
