Grid computing is rabidly emerging as the dominant paradigm for wide area distributed computing. It is a goal to provide a service to enable pervasive access to and coordinated resource sharing of geographically distributed software, hardware and information resources. Grid computing technology offers an innovative solution for digital library. Therefore corresponding research about integrating digital library management system into grid computing technology is started in recent years. The research objectives are mainly focusing on why we do need grid computing technology and its essential benefits to the digital library management systems. The paper designs a solution to the digital library management system based on grid computing, including User–Level module, Grid–layer module, Semantic Web module and Digital Library module four parts. The proposed innovative methodology brings many advantages and solutions to the digital library management systems.
