With the paperless information carrier and the networking of information dissemination, it is an inevitable trend for traditional libraries to transform into digital libraries. Therefore, our library is based on the existing collection of documents, guided by the key disciplines of the school, and by means of modern information technology, and always adheres to the concept of running the library according to local conditions, consciously adapting, actively serving and obeying the social development and economic construction of the whole province. The document management integration system 6.0 (enhanced version) of Dalian Bofeite Company is adopted. The system has circulation management, interview, cataloging, book reservation, public consultation, reading room management and other modules, which have been used in the library and run well.
