Few studies have addressed the topic on leadership within the field of librarianship. With a hope to add to the narrative literature of the leadership, the researcher employed literature review and analysis, questionnaires, and statistics analysis, to explore the leadership style of middle managers in the university libraries in Taiwan area. 343 university librarians and 85 department heads participated in this survey. The survey data indicates that there is a discrepancy between middle managers' self-expressed leadership behavior profiles and those perceived by subordinate librarians. And some subordinate librarians' demographics may affect their perceptions of leadership behavior demonstrated by department heads.
