At present, libraries at home and abroad have deployed research about the mainstream commercial and open-source library services platforms of next generation and have explored how the library integrated system will transform into the next generation and the advantages of the existing products. By combining the current situation of the library integrated system in China with analytic hierarchy process and the experts' argumentation, this paper constructs the evaluation index for the next generation services platforms. It also evaluates four kinds of products on the market including ALAM, Kuali OLE, OCLC WorldShare and Sierra. Based on the results of the evaluation, the author puts forward some in-depth thinking hoping to provide guidance for the choice of the next generation library services platforms.
