微软气喘吁吁地追着Google跑，推出了Windows Live Academic的测试，面向学术领域，用来对抗Google Scholar。

Windows Live Academic is now in beta. We currently index content related to computer science, physics, electrical engineering, and related subject areas.

Academic search enables you to search for peer reviewed journal articles contained in journal publisher portals and on the web in locations like citeseer.

Academic search works with libraries and institutions to search and provide access to subscription content for their members. Access restricted resources include subscription services or premium peer-reviewed journals. You may be able to access restricted content through your library or institution.

对用户来说，多个选择总归不是什么坏事，大家可以试用一下作个比较。不说检索结果，单看界面，微软这次做的不错，因为学术的搜索的用户往往需要更多的信息，微软的界面分为左右，左边为检索结果，而当鼠标在相应结果上的时候，不需电击，右侧的部分就显示了该论文的相关信息，有BibTeX的按钮，很方便。而相比之下，Google在很多时候会直接给你指到PDF文件，从速度上很不经济。大家可以深入的比较一下检索结果的差别。
