| Abstract: | Since federated searching and next generation library catalog technology are dictated by the slowest-responding resource,and there are issues with the ability of these resources to merge,it is difficult to meet with the need of young users.However,Web scale discovery service which based on the developing of cloud computing is the integrating and transcendence of them.There is a very large base of content indexed.It can provide similar academic search experience like Google Scholar,and also has a vertical academic index feature.Web scale discovery service such as WorldCat Local,Summon,EBSCO Discovery Service and Primo Central have a powerful search function,single search box and other characteristics,and the improvement has been achieved in American libraries.Data coverage and reliability are also worthy of consideration.Although Web scale discovery in China has just begun,it can improve the utilization rate of the library’s database.The development of Chinese Web scale discovery service is an urgent matter. |
