First, what is the document delivery service? Document delivery service is to ask for and deliver all kinds of documents that cannot be obtained directly in our library for readers. As long as readers accurately provide us with information such as the title and source of the required documents, we can obtain domestic and foreign documents for readers and provide them to readers in time. ?

Second, the role of library document delivery service. Document delivery is a document service that delivers the documents needed by teachers and students to users in a specific way. Compared with other ways of obtaining files, it is fast and simple. By carrying out the document delivery service, the school not only helps to promote the development of teaching and solve the contradiction between the shortage of documents and the increasing demand for documents, but also provides strong support for the school's scientific research service. The shortage of funds is one of the problems faced by many university libraries. As an auxiliary means, document delivery has become the main form of document resource sharing. With the help of modern network facilities, users are connected with resources, which makes up for the shortage of university library resources, expands the library's literature resources, is conducive to optimizing the allocation of literature resources, realizes the enjoyment of resources, and enables readers to obtain domestic and foreign literature information resources more conveniently and quickly.
