Secondary literature is processed by information workers, which brings together relevant contents and can comprehensively reflect the literature clues of a certain discipline, specialty or theme within a certain time and space; Because the secondary literature is processed by information workers, it can systematically reflect the latest research results of a certain discipline, specialty or subject within a certain time and space.
As an information style, secondary literature aims to provide a summary of the contents of the literature. Its basic function is to provide intensive scientific research information, facilitate researchers to obtain original documents, improve retrieval efficiency, make researchers spend less time and energy, and obtain more and more comprehensive original information and materials, which is conducive to improving the efficiency of scientific research and information exchange.
Secondary literature is widely used in primary literature such as scientific research papers, research reports and patent application documents, and has become a pioneer of primary literature. The secondary literature provides help for researchers to retrieve scientific and technological information and understand scientific and technological trends, and objectively expands the scope of scientific and technological information exchange. Researchers can quickly find relevant original documents through scientific abstracts.
