图书馆学研究对象：回顾、评述与模型建构

[Purpose/Significance] Clarifying the research object of library science, so as to make up for the shortcomings and deficiencies of the "theory of elements", "theory of library", "theory of library cause", "theory of technology" and "theory of knowledge" in the past, and consolidate the foundation of the discipline and enhance the legitimacy of the discipline. [Method/Process] Based on literature review and viewpoint review, a conceptual model of library science research object is constructed from the perspective of management. [Result/Conclusion] Library science is an applied interdisciplinary subject with multi-dimensional research themes and multi-situational dependence. Library science should be library management, and its research object should be "management theory", which includes four research themes of library organization, librarian, management and management object. Among them, library is the context and carrier, and librarian is the core and purpose. Management is means and basis, and the object of management is a complex system. The human nature assumption of librarians is the "first nature" of library science.
