MARC 378 Fuller Form of Personal Name

It may be needed when a part of a name is represented only by an initial or abbreviation in the form chosen as the preferred name, or when a part of the name is not included in the form chosen as the preferred name. Field 378 is used whether or not the authorized access point includes expansion. This field applies only to the name in the 1XX. This field is not repeatable.
