• 19 references in common across the 3 databases.

Other databases• Citing articles are a feature in many databases:

• Medline, Embase, PsycInfo, BIOSIS Previews• …and other databases on the Ovid site• Full-text databases such as ScienceDirect, Wiley Online

Library, JSTOR• Number of times it has been cited in that database. • Look for links such as “Cited by”, “Citing articles”

Quality or quantity?•Meho, L. I.; Yang, K. (2007). "Impact of Data Sources on Citation Counts and Rankings of LIS Faculty: Web of Science vs. Scopus and Google Scholar".

•Journal of the American Society for Information Science and Technology 58 (13): 2105–2125.

•doi:10.1002/asi.20677

Meho & Yang conclude:

•WoS remains an indispensable citation database.

•WoS and Scopus complement not replace each other.

•Scopus and Google Scholar identify many citations not found in WoS.

•GS unique citations not of same quality or weight, but could be useful in showing broader international impact .
