【Abstract】 In the era of big data, the ways and channels that people collect and obtain information have changed dramatically, the survival and development of libraries are facing new challenges, and the information construction of digital libraries is an important way for libraries to seek for survival. In this regard, this paper will analyze information construction and guarantee system construction in digital libraries. It first explores the basic status of information construction and guarantee system construction in digital libraries with the help of cases, understands information construction and the basic framework of the guarantee system in libraries, and then explores optimization strategies,so as to achieve the improvement of the completeness of information construction and guarantee system construction in digital libraries.更多还原
