In particular, the combination of traditional libraries and modern digital libraries has injected new vitality into the development of enterprise libraries and played an important role in the informatization construction of enterprises. Digital library is the direction of library modernization in the 2 1 century, and it is the only way for China library to change from tradition to modernization. It is an important carrier of knowledge economy, and its construction provides a brand-new means for knowledge dissemination. With the development and popularization of digital library, its position and role in the information society will become more and more important and become an important part of China's information industry [5]. The existence and information management of the library aims at maintaining the exchange relationship between the library and various markets, adjusting and perfecting information products, meeting the requirements of the continuous development and change of society, in exchange for direct or indirect returns from society, improving library conditions and developing library undertakings. Therefore, library information management is an important management activity with a clear goal, that is, it can effectively develop and utilize various resources of the library and create greater social benefits and economic values.

Although enterprise libraries have relative disadvantages compared with social libraries, such as narrow readership, few collections and lack of universality, the source of funds is greatly influenced by the business performance of enterprises and the concept of decision makers, and the quality of librarians is relatively low. However, enterprise libraries should also give full play to their own advantages, such as professional advantages, preferences of specific readers, strong enterprise backing, easy to play the auxiliary role of R&D, and provide decision-making for enterprise production and operation. At the same time, enterprise libraries must also improve their own level, improve service quality, strengthen management ability, strive to serve the society and realize social value, so as to achieve the purpose of self-development and self-improvement.
