The citation information in Google Scholar is extracted from the scholarly journal articles within the Scholar database and from the U.S. patents contained in the Google Patents database. Users have the option to eliminate the patents as the source of citation data and/or the option to include citations from legal journals and opinions from the federal and state courts. If a publication has been cited by these sources, it will contain a "Cited By Link" in its entry; clicking on that link will display the citing journal articles and patents (and the court opinions, if selected)
How to Find Citation Counts via Google Scholar and "Who is Citing Whom"
See the instructions for connecting Google Scholar to Royal Holloway and Senate House Resources.
Google Scholar Citations
Google Scholar Citations allows authors to keep track of citations to their articles, graph citations over time, and compute several citation metrics (the h-index, i10-index, and the total number of citations for both All and Recent citations) by creating an author profile in which they identify all their articles for Google Scholar to track on an ongoing basis.
Google Scholar Universal Gadget Citation Counter
You can add this gadget to your IGoogle page. The gadget gives the total citation count, the number of cited publications and the H-index for an author.
Publish or Perish (PoP)
PoP is downloadable software providing enhanced analysis of Google Scholar citation data. For more information and access to the software, see Publish or Perish on the Harzing.com website.
CIDS (Citation Impact Discerning Self-citations)
CIDS will analyze publications for self-citation data; this includes the h- and g-indexes calculated both with all cites and then without self-cites. The service is free, however, limitations are many. According to the FAQ page, only one search per email is allowed. There is also a limit of 200 items (in the tutorial, it says 500 items) for the analysis. The analysis takes about 1 minute per item to calculate.
