The mission of philosophy is to lead the trend of the times and history. The theoretical construction of philosophy of library science will also assume the historical responsibility of leading the development of contemporary library science theory and practice.

Based on this, a theoretical framework based on practical materialism was attempted.

This book is a comprehensive work written by the author on the basis of his works Study on Axiology of Library, Study on Ontology of Library,and Study on Epistemology of Library. It is suitable for all who care about library existence and development to read.
