Abstract: Considering that digital resources are mainly purchased, seriously homogeneous and expensive, the development of digital special collection brings opportunities to libraries. Although many digital special collections have been built in large-scale digital projects such as CADAL and CALIS by domestic university libraries, it is still necessary to continuously explore the use of special collection to support teaching, scientific research and cultural inheritance, to break the information isolated island, and to release its great value. This study investigates and analyzes the libraries of 100 well-known universities in the world from the aspects of basic information of digital special collection platform, library homepage entrance, disclosure mode, openness, resource types and their Chinese resources. It constructs a generalized linear prediction model between special collection resources and library homepage flows, and explores the construction status and future development direction of special collections in university libraries, providing reference for the construction of special collections in Chinese university libraries.
