直到最近，Web of Science是唯一一个可以跟踪已发表文章引用计数的数据库。目的比较Web of Science、Scopus和Google Scholar.Design Cohort对1999年10月1日至2000年3月31日发表在JAMA、Lancet和新英格兰医学杂志上的328篇论文的引文计数。截至2008年6月，每篇文章的总引用数均来自Web of Science、Scopus和Google Scholar。结果Google Scholar和Scopus检索到的每篇文章的引文数中位数为160篇，平均每篇文章的引文数中位数为160篇（四分位数范围[IQR]，83至324）和149（IQR，78至289）分别比Web of Science（中位数，122; IQR，66至241）（P
Context Until recently, Web of Science was the only database available to track citation counts for published articles. Other databases are now available, but their relative performance has not been established.Objective To compare the citation count profiles of articles published in general medical journals among the citation databases of Web of Science, Scopus, and Google Scholar.Design Cohort study of 328 articles published in JAMA, Lancet, or the New England Journal of Medicine between October 1, 1999, and March 31, 2000. Total citation counts for each article up to June 2008 were retrieved from Web of Science, Scopus, and Google Scholar. Article characteristics were analyzed in linear regression models to determine interaction with the databases.Main Outcome Measures Number of citations received by an article since publication and article characteristics associated with citation in databases.Results Google Scholar and Scopus retrieved more citations per article with a median of 160 (interquartile range [IQR], 83 to 324) and 149 ( IQR, 78 to 289), respectively, than Web of Science ( median, 122; IQR, 66 to 241) (P
