    • 20. 存在的问题 (Cons Continued)
      • 在检索结果排列方面,由于根据引文被引用情况排列,因此那些排在前面的论文往往是年份较早的,同时 Google Scholar 又没有提供按日期排列的服务 。
      • 改进:“近期文章”按钮
      • 排序方式无法自订

    • 23. 总结 (Conclusions)
      • Google Scholar 的面世,为科研用户提供了一个强有力的学术搜索工具,它可以帮助用户第一手的全面了解某一领域的学术文献,可以帮助用户屏蔽掉网上许多无关信息,可以帮助用户找到信息的来源,可以帮助用户发现其还不了解的内容。 (It helps us find out what we don’t know.)
