An interesting article in the online D-Lib Magazine (11.9 (2005)), “An Examination of Citation Counts in a New Scholarly Communication Environment” by Kathleen Bauer and Nisa Bakkalbasi of Yale, this preliminary study examines citation searching in Web of Science, Scopus, and Google Scholar. I quote from their conclusion:

Based on our preliminary examination and discovery of higher citation counts, we recommend that researchers should consult Google Scholar in addition to Web of Science or Scopus, especially for a relatively recent article, author or subject area. A search of Google Scholar will likely reveal both traditional journal articles, some of which will also be covered in Web of Science and Scopus, and additional unique material, but the scholarly value of some of the unique material remains an open question. Consulting Google Scholar may prove most useful for disciplines such as physics, where nontraditional forms of publishing are widely accepted. However, it is important for all researchers to note that until Google Scholar gives a full account of what material it is indexing and how often that index is updated, it cannot be considered a true scholarly resource in the sense that Web of Science and Scopus are. An understanding of the material being covered is central to the validity of any search of scholarly material.

In light of the frequent requests for citation counts on publications (particularly on faculty’s own publications), it may behoove one to search Google Scholar as a supplement to Web of Science. -Derik A Badman
