What is citation analysis?
Citation analysis is a way of measuring the relative importance or impact of an author, an article or a publication by counting the number of times that author, article, or publication has been cited by other works.
Why conduct citation analysis?
Citation analysis may be conducted for following purposes:
- To establish the impact that a particular work has had by identifying which other authors based their work upon it or cited it within their own papers.
- To learn more about a field or a topic by identifying seminal works in that area.
- To determine what impact a particular author has had within his/her own discipline and beyond by looking at his/her total number of citations broken down by discipline and by country.
- For promotion and tenure purposes by looking at the quality of sources where a scholar’s work has been published and cited
Sources for Citation Analysis: There are several tools available for citation analysis, some are subscription-based and others are free. Each tool has its strengths and weaknesses and none of them covers the entire universe of scholarly publications. Therefore, it is important to use more than one tool to get a fuller picture of the scholarly impact of an author or a journal. Below is a table highlighting the characteristics of two citation analysis tools:
