摘要：[目的/意义]图书馆学当前正面临学科发展的瓶颈，重新思考图书馆学的学科定位和发展方向是图书馆学界共同关心的问题。[方法/过程]本研究采用历史研究方法，以中国现代图书馆学创建初期的图书馆学教育重镇东南大学为切入点，围绕东南大学的两位图书馆学家洪范五与张厚生，系统收集史料，全面考察他们的学术和职业生涯，以此描绘我国图书馆学教育与图书馆实践的曲折发展过程。[结果]研究表明，图书馆学教育和图书馆实践两者是相辅相成、相互成就的；两者割裂分离，对于图书馆学科研究而言将会导致研究领域的泛化和研究内容的空心化；对于图书馆实践而言，则会失去图书馆学的理论指引与图书馆馆员的专业认同。[结论]构建“图书馆学科共同体”，夯实专业基础，继承文献研究学术传统，将图书馆学教育与图书馆业务统合起来，是解决图书馆学学科困境的路径之一，也是培养现代图书馆学人和图书馆专业馆员的重要标志。

Abstracts: [Purpose/significance] Library science is facing the bottleneck of discipline development at present.Rethinking the discipline orientation and looking for the future development direction is a common concern. [Method/process] Using the historical research method,and taking Southeast University as investigation sample, which is a keyposition of library science education in the early stage of modern library science in China. Based on sufficient literatureabout Hong Fanwu and Zhang Housheng, two directors of Southeast University library, describes the tortuous process oflibrary science education and library practice in China. [Result/conclusion] Historical investigation shows that libraryscience education and library practice complement each other. The separation of the two,will inevitably affect the development of library and library science. For library science research, it will generalize the research field and hollow theresearch subject; and for library practice, it will lose the theoretical guidance of library science and the professionalidentity. Building a"library science community",consolidating the professional foundation, inheriting the academic tradition of literature research, and unifying library science education and library practice, that is not only one way tosolve the dilemma of library science education,but also an important symbol of cultivating modern library scholars andprofessional librarians.
