Measuring Your Impact: Citation Analysis

Overview of h-index, Eigenfactor, Impact Factor (IF), Journal Citation Reports, Citation Analysis, and other tools.

Citation Analysis

Citation analysis is the study of the impact and assumed quality of an article, an author, or an institution based on the number of times other authors cite, or mention it in their work.

Why Use it?

  • To find out how much impact a specific article has had by looking at the number of times the article has been cited by others.
  • To find out more about a field or topic. For example: reading the papers that have cited a seminal work in a particular area
  • To determine how much impact a particular author has had by looking at the number of times their work has been cited by others
