Citations to research publications and other citation-based metrics are often used as a measure of the impact of research publications. Not all publication metrics are citation-based, for example collaboration and output indicators. Metrics can be calculated for an individual article, for an author or journal. For more details about metrics go to the Metrics section of this guide.
Responsible use of metrics
It is important to remember that quantitative measures are only one method of measuring research reach, and shouldn't replace qualitative measures such as peer review. When using metrics, you should consider:
The weaknesses, strengths and appropriate use of the metrics;
What you are attempting to measure and whether metrics are appropriate; and
Using multiple metrics, to provide a fuller picture of what is being assessed.
