Citation tracking can facilitate the review and evaluation of pertinent literature for the following reasons:
- It can be an effective way of using a highly cited "landmark" or influential article to find more recent, related articles that cite the original work. It also can be an effective way of identifying important scholars in a particular field who have subsequently cited the work.
- It can be a useful means for evaluating a study's "impact" within a particular discipline based upon the number of times a research study has been cited by others. A highly cited study may indicate that the research findings are unique, groundbreaking, or controversial in some way.
- It can be an effective means of determining the interdisciplinary value of a particular study because you can identify the amount of subsequent citations to an article from publications in other disciplines or areas of study. Studies that have been cited in a variety of disciplines is also a strong indication of the research study's overall impact thoughout the social sciences [and perhaps beyond].
When tracking citations, keep in mind the following points:
- Authors do not always use the same name throughout their careers so be sure you work from a complete and accurate list of an author's publications.
- In the case of the Web of Science citation database, it uses APA style for citing authors [last name and first initial only], so a J Smith could be John, Jeff, Jane, Julie, Jason, etc. Be sure to truncate the initial [adding an asterick *] to see a more complete list of authors, then locate a record on a topic you know the author writes about and click on that author to exclude articles written by other J Smith's. Fortunately, the database indexes more than the first author of a paper so if a second or third author has an uncommon name, you could search the unusal name instead of using an author's common name.
- Citation services are primarily based on selected journal literature. If the author is cited in books, foreign language periodicals, or non-scholarly publications, the usefulness of your citation analysis is limited. In addition, citation databases such as Web of Science rarely cover articles published in scholarly open-access journals [journals published freely on the web], although this is slowly changing. In this case, be sure to check the "cited by" references in Google Scholar as it often includes citations founds in other publications besides scholarly journals.
- Pay attention to how recent the citations are when reviewing a particular study. An article published in 1990 may have 130 total citations but if the most recent citation is from 2008, then this is an indication that the study's impact has faded or there is a lack of progress in the field [unlikely]. The absence of recent citations does not necessarily mean a study no longer has value, but it's a strong indication that more recent research has overtaken prior studies or that external factors have influenced scholars to focus on other areas of inquiry.
