The following resources below are databases which contain citation counts for articles.

• Google Scholar

For journal abbreviations, defer to the ones listed in Web of Science.

Some tips from Google:

• An author search is one of the most effective ways to find a specific paper. If you know who wrote the paper you're looking for, you can simply add their last name to the search terms.
  
  For example: The search [friedman regression] returns papers on the subject of regression written by people named Friedman. If you want to search using an author's full name, or last name and initials, enter the name in quotes: ["jh friedman"].
   
• When a word is both a person's name and a common noun, you might want to use the "author:" operator. This operator only affects the search term that immediately follows it, and there must be no speace between "author:" and your search term.
  
  For example: [author:flowers] returns papers written by people with the name Flowers, whereas [flowers -author:flowers] returns papers about flowers, and ignores papers written by people with the name Flowers (a minus in front of a search term excludes results that contain this search term).
   
• You may use the author operator with an author's full name in quotes to further refine your search. Try to use initials rather than full first names, because some sources indexed in Google Scholar only provide the initials.
  
  For example: To find papers by Donald E. Knuth, you could try [author:"d knuth"], [author:"de knuth"], or [author: "donald e knuth"].

• Publish or Perish

A software program that retrieves and analyzes academic citations. It uses Google Scholar to obtain the raw citations, then analyzes these and presents the following statistics:

• Total number of papers
• Total number of citations
• Average number of citations per paper
• Average number of citations per author
• Average number of papers per author
• Average number of citations per year
• Hirsch's h-index and related parameters
• Egghe's g-index
• The contemporary h-index
• The age-weighted citation rate
• Two variations of individual h-indices
• An analysis of the number of authors per paper.

Scopus, produced by Elsevier Science (1960-present), dentifies scientific articles in over 14,000 peer-reviewed journals from more than 4,000 international publishers. Multidisciplinary coverage includes health, agriculture, chemistry, physics, life sciences, mathematics, engineering, earth and environmental sciences, social science, psychology, and economics, business and management. Includes citation counts via "citation tracker" button and one can set up e-mail alerts.

Within Web of Knowledge is Web of Science, which indexes journals and provides complete bibliographic data, full length author abstracts, and cited references. Indexes currently available are: Science Citation Index Expanded, Social Sciences Citation Index, and Arts & Humanities Citation Index. Can also be used to find reviews. The Science Citation Index Expanded and Social Sciences Citation Index are available from 1970 to the present. The Social Science Citation Index will be the one used the most.

Note: Many business journals are not indexed by the Web of Science. See other resources for citation counts.
