You will need to use a variety of resources to document your citation rate and present results. Below are 3 resource to assist you. In the right column is a list of databases that provide citation counts for the journals they index.
Web of Science: Cited Reference Search: The ISI Web of Science database is the original citation research source and along with Google Scholar is the most interdisciplinary and most comprehensive citation resource available. Web of Science extracts the citation information from the articles in over 6,000 journals from almost every discipline. A citation search in the ISI Web of Science is not a complete citation search: Only citations from a set of 7,500+, primarily English-language, journals are counted. Citation data from books, conference proceedings, dissertation & theses, patents and technical reports are not included in the database; therefore fields that publish heavily in the journal literature (such as the sciences) are better covered than those that don't (such as History). Subjects are not covered evenly by date; the science journals are covered much farther back in time than are the journals in the arts, engineering, humanities, and social sciences. Some subject areas are poorly covered including business and education. Step-by-step instructions.
Google Scholar
Type the author's name into the Google Scholar search box and you will get a list of publications by that author with an indication of how often it was cited. If for example your article was cited 30 time, when you click on the number '30', you will see the citations for that article. Keep in mind, these citations are obtained by Google when they scrape web sites. The publications citing you may be journal articles, books, web pages, newspaper articles, etc.
Publish or Perish (aka Harzing Publish or Perish)
Offers free software you can download to your computer that will retrieve and analyze academic citations taken from Google Scholar. It presents the 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 and other parameters related to faculty productivity. This is an interesting alternative to the Web of Science: Cited Reference Search database (mentioned above).
