阐述上海市中心图书馆建立的意义,分析其向社区基层延伸中将面临的四大问题,着重论述上海市中心图书馆的区县分馆在这一延伸过程中应扮演的角色:区县分馆应是连接上下的桥梁,并成为地区业务的指导中心、资源建设分中心、文献信息提供分中心、采访编目分中心、技术支持分中心、图书物流分中心。 This article elaborates the significance of the establishment of Shanghai Central Library, analyzes the four major issues that the Central Library of Shanghai will face when extending to the grass roots of the community, and focuses on the role that district and county branches of Shanghai Central Library should play in this extension: The pavilion should be a bridge linking up and down, becoming the guidance center, resource construction sub-center, document information sub-center, interview catalog sub-center, technical support sub-center and book logistics sub-center of regional business.
