What does the MARC tag 100 represent?

The MARC tag 100 is designated for the representation of a personal name with a single surname. In bibliographic records, this tag is used to indicate the primary author or creator of a work, providing essential information for cataloging and retrieval. By identifying the individual's name in this format, libraries can efficiently organize resources and allow users to search for works by specific authors.

The significance of properly using the 100 tag lies in its role in ensuring that cataloging standards are followed, promoting consistency across library databases. This tag is crucial for visibility and accessibility, enabling patrons to find materials related to a particular person effectively. The function of the MARC 100 tag is foundational in library science, forming a central piece in the intellectual organization of bibliographic records.
