In recent years, with the changes of society, economy, technology and personnel knowledge structure, the development of library management system has been directly or indirectly promoted. To this end, many advanced modern management sciences have been introduced and applied in large quantities. At present, knowledge management conforms to the rapid development of society, and libraries should break through the traditional service form and meet the public's demand for relevant knowledge with knowledge service. Therefore, in order to improve the service efficiency and benefit of the library, the application of knowledge management should be introduced into various management of the library, including librarian team construction, collection construction, document cataloging, circulation lending, reference service, human resource management and reader management and service.

First, the construction of librarian team

The purpose of librarian's knowledge management construction is to construct a reasonable and scientific knowledge structure, realize the knowledge innovation within librarians and improve the knowledge level of librarians. Therefore, we can improve the knowledge level of librarians in all aspects, construct new ways of employing people, and urge people to do their best to tap the potential of librarians.

Second, establish a collection of books.

The application of knowledge management can effectively promote relevant personnel to learn business knowledge, organically transform explicit knowledge into tacit knowledge, and promote the innovation of related theories and practices. Through research, we can have a more comprehensive understanding of the collection of books in the library, search the collection more conveniently, and improve the utilization rate of books by readers. According to the investigation and regular statistics on the utilization rate of library books, intangible knowledge can be classified into the library book management system. In the work, we can not only avoid the trap set by the library, but also evaluate the quality of books and services by investigating the utilization rate, so as to adjust the construction direction of the library in time and effectively.

Third, document cataloging.

Efficient document cataloging can quickly and effectively show readers the library's book resources. The application of knowledge management in document cataloging includes indexing periodicals, books and electronic resources, classification and topics, and cataloguing documents by using MARC metadata. The core value of knowledge management is human resource management, and document catalogers belong to it. If the catalogers are experienced, they can provide readers with multiple effective retrieval points in document cataloging, which is conducive to improving the operating efficiency of the library and enabling readers to retrieve the required document resources quickly, effectively and independently. Under the network environment, the library's document cataloging has broken the original category, no longer limited to paper document cataloging, but extended to network resources and electronic resources. This requires document catalogers to combine tacit knowledge and explicit knowledge to carry out digital and networked document cataloging. This can effectively integrate paper literature resources and network electronic resources, which is convenient for readers to choose.

Fourth, circulation lending.

The work of library circulation department is not only the borrowing of book resources, but also the direct contact with readers face to face, and readers will consult librarians, so librarians should also act as navigators. It can be seen that the application of knowledge management in library business, the role played by the circulation department and the services provided are more direct and effective. In this way, we can answer readers' questions at any time, introduce explicit knowledge to readers logically through intangible knowledge, and let readers get satisfactory service.

Verb (abbreviation for verb) refers to service.

Reference service is the application of knowledge management, which provides readers with tacit knowledge and existing explicit knowledge. Its contents include: interlibrary loan, subject service and document delivery. The application of knowledge management in reference service includes the integrated development of tacit knowledge-related resources and the organization and processing of explicit knowledge-related resources. These contents are just in line with the contents of the reference service. Introducing knowledge management into library reference service will greatly improve the efficiency of reference service, establish knowledge exchange environment, promote cooperation among librarians, provide brand-new ideas and ideas for the improvement of library electronic network reference service, and solve various problems faced by libraries in time and effectively.

Manpower deployment of intransitive verbs

As far as the library is concerned, its employees are the main body to realize new ideas, new services and new management in the new environment, and they are the driving force of library structure and development, so the core of knowledge management is human resource management. The ultimate goal of library knowledge management is to apply progressive knowledge innovation to realize the core values of library resource utilization-equal enjoyment and free acquisition of knowledge, respect for readers' personal privacy, and establishment and improvement of a harmonious cultural environment. The human resource management of librarians is the carrier to achieve this goal. Therefore, human resource management plays a unique and irreplaceable role in the application of knowledge management to library business. Therefore, libraries should strengthen human resource management.

Seven, reader management and service

As the main object of library service, readers are an important prerequisite for their survival. Readers come from different social strata and have different demands for information. In the application of knowledge management, the library should make readers abide by the rules and regulations of the library, at the same time, learn from some readers' suggestions on library construction scientifically and reasonably, fully mobilize and utilize the relevant wisdom and talents of some knowledge workers in a variable service form, sort out, analyze and solve specific problems, and make full use of the relevant data provided by readers to improve the management and service of the library.

Eight. Concluding remarks

As a brand-new management mode, knowledge management has been introduced into library management in recent years. The application of knowledge management plays a key role in library business. Knowledge management serves the overall goal of library management: knowledge management puts forward new ideas for the theory and practice of library management, optimizes and integrates invisible knowledge and explicit knowledge, provides new ideas and methods for librarians to manage the library, provides a foundation for tacit cooperation among the workshops of the library, and provides a guarantee for the library to transform into a knowledge-based organization.
