Measuring Research Impact

2. Introduction
• A professor may ask, "Who is citing my articles? How many
times have I been cited? What is my h-index score?"
• A student may enquire, "How do I know if this article is
important?"
• A scholar may ask, "Which journal should I publish in?"
• A different scholar asks, "What are the best journals in the
field of Library & Information Science? "

ranking and tracking", College & Research Libraries News, vol. 72, no. 8

3. 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 works
and/or authors have been cited by others.
• Counting citations is often called "citation analysis."
• In your scholarly research, you may need to measure
the importance of a publication by counting the
number of times it has been cited by other scholars.

4. Citation Analysis
• When you count the number of times an article has been cited
in published research, you gain information about that article's
impact on its discipline.
• If an article has a high number of citations, you may conclude
that it has been the subject of discussion or criticism in its
discipline.
• "Counting citations" sounds simple; however, citation analysis
tools count citations from different sets of publications.
• When you are performing a citation analysis, you may wish to
use several resources to count citations in order to fully
capture an article's impact.

5. Citation Analysis - Why use it?
• To find out how much impact a particular article
• To find out more about a field or topic
• To determine how much impact a particular author
has had by looking at his/her total number of
citations.
Several tools can help you to find out how many times
a specific article, author, or journal has been cited.
These tools are referred as citation indexes/databases.
