Beihang University Library was founded in 1952, formerly known as Beihang University Library. The library is rich in collections, and a document information resource guarantee system combining paper documents with electronic documents, physical collections with virtual collections has been established. According to the development trend of the school and the needs of teaching and scientific research, the construction of electronic documents has been greatly strengthened. The library has transformed from a traditional library to a new open library that breaks through the limitations of time, space and media, and is moving towards the goal of building an open, research-oriented and modern library that is highly compatible with "internationally renowned and domestic first-class" universities.
