When organizing personal names, what are the two main indexing units?

When organizing personal names for indexing purposes, the primary focus is on the arrangement and retrieval of names in an efficient manner. The correct response highlights that the two main indexing units are the last name and the first or middle name/initial.

This approach is grounded in the standard practice of alphabetizing names, where the last name typically serves as the primary unit, facilitating easier sorting and searching within databases or filing systems. The first name or middle initial acts as a secondary unit that helps distinguish between individuals who might share the same last name, ensuring clear differentiation.

By using both the last name and the first or middle name/initial, indexers can maintain a systematic order that minimizes confusion and enhances accessibility to the data. This method is widely used in professional settings, making it essential for understanding how to organize records effectively.
