Abstract: In the transition from traditional library to modern library, local libraries open their collections to the outside world, which greatly facilitates the study of local chronicles scholars and expands the reading scope of local chronicles. The periodicals set up by the library provide a platform for academic discussion on the development of local chronicles and accelerate the dissemination of local chronicles. Local libraries provided and compiled various local chronicles for the development of modern local chronicles, which provided necessary auxiliary tools for academic research and promoted the development of local chronicles bibliography. With the publication of all kinds of library periodicals and the compilation of all kinds of local chronicles, a series of local chronicles catalogs and reviews of local Chronicles works were produced, which indirectly expanded the space of local chronicles critics.
