Paper Keywords: Library Basic Business Construction Abstract: The library is an important place and main helper for the construction of human spiritual civilization, and its role is self-evident. In recent years, with the continuous development of society and the constant updating of knowledge, the operating mode of the library has to be changed. Only by strengthening the basic business of the library can we provide readers with better service capabilities and functions to meet the requirements of today's society for the library. This paper discusses how to strengthen the basic business construction of the library, hoping to bring some inspiration and help to everyone. Libraries are closely related not only to human history, but also to our daily life. As one of the important places to provide people with spiritual food and daily knowledge, it is an indispensable part of our life. Therefore, with the rapid development and dissemination of information today, the development of libraries must also keep pace with the times and always be the vanguard of our spiritual civilization construction. The basic business work of the library mainly includes five aspects: interview, editing, reading, storage and management. Only by doing a good job in the basic business of the library can we really improve the service quality, develop the information cause of the library, and let the library keep up with the pace of the times and complete its due mission. The following is a detailed discussion on how to strengthen the basic business construction of libraries. 1 "Interview" in library's basic business Construction "Interview" in library's basic business mainly refers to library's interview work. Interview is the starting point and key point of the whole book publishing process. Only efficient and high-quality book acquisition can take care of the overall situation of the whole library, make overall arrangements, realize the rational allocation of funds and resources, and determine the quantity of the whole collection and the quality of books. In the construction of library's basic business "acquisition", there must be an independent department responsible for acquisition, which is also the premise of construction. Only with an independent interview department can the interview work be carried out effectively. For example, some libraries are not very clear about the division of labor. Many staff members are also responsible for interviewing, cataloging and borrowing; Due to the lack of skills in two places at once, they often adopt an intensive interview mode when conducting interviews, and concentrate on letting staff go to some bookstores and stacks to choose books for a period of time. Although this mode can complete this work quickly, the effect is not ideal. If we have an independent interview department, then the relevant staff can conduct an in-depth investigation on the overall structure, development direction and even interview methods of the collection without the interview task, and at the same time inspect the publishers of the library, and put forward scientific and standardized technical requirements suitable for the needs of the library, so as to know ourselves and know ourselves in the interview work and really improve the interview business of the library. In addition, interview methods should be rich. Browsing the stacks, participating in some large-scale book fairs and book ordering fairs, and participating in sample book fairs held by some better publishing houses, so that these famous publishing houses can hold book fairs, are all better interview modes; In addition, the library is a service-oriented industry, and people-oriented is the principle and important foundation of our work. Therefore, in the interview mode, we can make an interview plan according to the book recommendation form collected from readers and the collected opinions. At the same time, we can also build a platform on the Internet, establish the connection between book suppliers, libraries and readers, and improve the quality and efficiency of the interview. 2 "Editing" in the basic business of the library Document cataloging is another basic business of the library, and the quality of cataloging directly affects the effect of reader service. In the construction of cataloging, there are two main methods that can be improved: the first one, which is also widely used now: computer cataloging. With the rapid development of computer technology and modern communication technology, their application has also extended to the cataloging work of libraries. It is mainly an activity process of cataloging documents according to the cataloging rules and methods of our library's cataloging drawings. By this method, documents in a certain space, time, subject or subject range are recorded and arranged in a certain order, which is helpful for document retrieval. The second is cataloguing outsourcing, which is also an important direction for future development. Specifically, the library will entrust the task of cataloging to the booksellers who provide books for the library, and they will make their own bibliographies for the books provided. Include pasting bar codes, pasting library stamps, pasting magnetic strips, printing book labels, pasting book labels, etc. In this way, the library can make full use of external enterprise resources and management efficiency without affecting its basic service work, and at the same time, it can concentrate most of its manpower to complete various reader-centered services. However, it is difficult to establish a completely unified cataloging standard between booksellers and libraries, which leads to many contradictions between booksellers and libraries, and it is impossible for booksellers to coordinate and unify, which makes the development of cataloguing outsourcing business slow. In this environment, many libraries have developed another way for us: joint cataloging, that is, sharing information with booksellers, so that booksellers can fully understand the characteristics and laws of library collections, so as to design reasonable book classification rules, make cataloguing in line with library characteristics, and ensure the accuracy of materials.
