Journal rankings (impact factors, citation comparisons, etc.) are used to help quantify the impact of specific journals and articles on the scholarly literature.
- Different ranking strategies are available.
- Numerical values of rank differ with methodology, source data, filtering, etc.
- Cross-discipline comparisons should be done with caution.
- Formats commonly used in engineering/applied sciences (proceedings, technical reports, etc.) don't "count" in journal impact factors.
