以“211工程”高校图书馆参加的联盟为样本,从其门户网站入手调查,结果显示联盟门户呈现出三个特点:注重统一检索平台的建设;依靠商用信息平台实现资源整合;个性化服务成为新宠。在此基础上,提出应该完善元数据的使用,提高资源整合能力;打造联盟自身的不可替代性;重视用户与联盟门户的互操作性;建立联盟绩效评估体系,从而不断优化和完善图书馆联盟门户建设。 Taking the alliance of “211 Project” university library as a sample, from the survey of its portal website, the results show that the Union Portal has three characteristics: paying attention to the construction of a unified search platform; relying on the commercial information platform for resource integration; and personalization Service has become the new favorite. On this basis, it is proposed that the use of metadata should be perfected, and the resource integration ability should be improved, the alliance’s irreplaceability should be built up, the interoperability between user and affiliate portal should be emphasized, and the alliance’s performance evaluation system should be established so as to optimize and perfect the alliance of library Portal construction.
