-With the rapid development and widespread use of Internet, readers, especially scientific researchers, depend more on Internet than on traditional library services for necessary information. The Web access of libraries has begun to lay more emphasis on digital reference and consultation services. More importantly, this new type of service is becoming the focus of many scholars' research at home and abroad. In this paper, we design a library digital resources management system based on the semantic Web technology, and analyze the access control model in our system by the semantic Web.
