“Beginning with the highest level of administration in your specific library, (for example, the Director/ Dean/University Librarian level) record the reporting or organizational structure of your library in relation to your cataloging unit, including all “hierarchical” levels within the cataloging unit itself or any units that primarily report to cataloging.  Do not include any divisions, units, or departments that are not in a direct reporting line to cataloging or between the cataloging unit and the top level administration in your library.”

Responses were compiled and split between institutional type.  The average number of hierarchical layers is reported below.
