Meaning:
Modern document delivery is developed from interlibrary loan with the support of information technology, but it is a better service than interlibrary loan. If teachers and students can't find the original documents (mainly papers) they need in the existing resources (paper resources and electronic resources) of the school library, they can apply for the document delivery service of the library.
By carrying out document delivery service, the contradiction between the shortage of library funds and resources and the increasing demand of readers for documents is not only alleviated, but also plays a very good supporting role in teaching and scientific research.
