Agency-assigned data element:
An agency-assigned data element is one whose content is determined by a designated agency and is the responsibility of that agency, for example, field 010 (Library of Congress Control Number). While it is usually input by the designated agency, it may be modified or transcribed by another organization. When the content designation and transcription of the agency-assigned data is performed by another organization, the responsibility for these functions is determined by the Responsible Parties Rule.
