Its purpose is to summarize the practical experience of library work and library cause, establish a scientific theoretical system of library science, promote the development of library cause, and improve the position and role of library in the progress of human society.
Library science is a developing science. Modern library science combines scientific contents with various attributes. With the progress of society and science and technology, especially the increasing demand for information and document exchange, the research and application prospect of library science will be broader.
This view, which focuses on the technical operation and working methods of the library, has been further developed. Albert, Morbesch and Edwards made a relatively complete experience summary on the theories and methods of book collection construction, classification and cataloging, book collection protection and reader service, and covered them with the concept of library management.
Dewey is a master who studies library management. He founded the School of Library Management of Columbia University in 1887, and the core of its teaching system is to explore the "practical utility and management" of library management. His view has been widely valued and influenced.
In 1930s, Butler in America and Sheila later believed that library management and technical methods should not be the main research objects of library science, and library science should study its theoretical basis and scientific principles to establish library philosophy, thus revealing the essential characteristics and development laws of libraries.
