1807, Schleitinger of Germany put forward the special term "library science"; From 1808 to 1829, he published "Comprehensive Trial Textbook of Library Science", which comprehensively discussed the compilation principles of library catalogue for the first time in the history of library science. He also attaches great importance to the special education for librarians, and thinks that library management is a special and unique subject. Since then, theoretical research and academic discussions have continued around this new modern discipline, represented by German Albert, Danish Moore Betsch, British Panizzi and Edwards. 1820, German librarian Friedrich Adolf Albert (179 1- 1834) published Librarian Education. 1829, Danish Christian Molbech (1783- 1857) published in Public Library, which further developed Albert's theory and formed the Albert-Molbert system of library science, which is the mainstream theory of western library science in the next century. The core of this system is "library science should study the practical technology in library work", and library science is "the sum of all the knowledge and skills that librarians need when performing library work tasks". Paniz, librarian of British Museum (1797- 1879), and Edward Edwards, librarian of Manchester Public Library (18 12- 1886). On the basis of attaching importance to document arrangement (cataloguing), they improved the position of document utilization (reading and circulation) in the library work system, and thought that the research object of library science should be the library work management system, that is, the internal management of document procurement-cataloguing-circulation workflow.
