科学信息研究所（ISI，现为宾夕法尼亚州费城的汤姆森科学公司）的引文数据库几十年来一直被用作起点，通常也是定位引文和/或进行引文分析的唯一工具。然而，ISI数据库（或Web of Science（WoS））可能不再足够，因为现在可以使用新的数据库和工具进行引文搜索。以25名图书馆与信息科学（LIS）教师的工作为例，作者研究了使用Scopus和Google Scholar（GS）对WoS测量的引用计数和学者排名的影响。总体而言，审查了10，000多份引用和据称引用的文件。结果表明，Scopus显着改变出现在排名中间的那些学者的相对排名，GS脱颖而出，在其覆盖的会议记录以及国际，非英语语言期刊。除了WoS之外，Scopus和GS的使用有助于更准确和全面地揭示作者的学术影响力。WoS数据的收集和处理时间大约为100小时，Scopus消耗了200小时，GS消耗了3,000小时。
The Institute for Scientific Information's (ISI, now Thomson Scientific, Philadelphia, PA) citation databases have been used for decades as a starting point and often as the only tools for locating citations and/or conducting citation analyses. The ISI databases (or Web of Science (WoS]), however, may no longer be sufficient because new databases and tools that allow citation searching are now available. Using citations to the work of 25 library and information science (LIS) faculty members as a case study, the authors examine the effects of using Scopus and Google Scholar (GS) on the citation counts and rankings of scholars as measured by WoS. Overall, more than 10,000 citing and purportedly citing documents were examined. Results show that Scopus significantly alters the relative ranking of those scholars that appear in the middle of the rankings and that GS stands out in its coverage of conference proceedings as well as international, non-English language journals. The use of Scopus and GS, in addition to WoS, helps reveal a more accurate and comprehensive picture of the scholarly impact of authors. The WoS data took about 100 hours of collecting and processing time, Scopus consumed 200 hours, and GS a grueling 3,000 hours.
