当今图书馆已从收藏单一印刷型文献,转向收藏多种媒体文献;从占有、拥有信息资源,转向重视存取质量,形成以用户为中心,以需求为导向的多媒体信息资源建设理念和模式。 Nowadays, libraries have shifted from collecting a single type of printed literature to collecting a variety of media documents. From possession and possession of information resources, they have turned to paying attention to quality of access and have formed a concept and mode of building a user-centered and demand-oriented multimedia information resource.
