01 A new perspective
As publishing and research trends change, the tools used to measure them must also change. The use of journal metrics by journal editors and research institutions becomes more complicated every day. Scholarly publishing can no longer rely on a single metric to serve all of its needs.
SNIP and SJR offer the value of context in the world of citations.
The tools:
- Apply to nearly 18,000 journals, proceedings and book series
- Are refreshed twice per year to ensure currency of metrics
- Eliminate the risk of manipulation
- Correct for citation behavior and database coverage
- Provide multidimensional insights into journal performance
- Allow for a direct comparison of journals, independent of their subject classification
- Are publicly accessible and are integrated into Scopus Journal Analyzer

This paper explores the new indicator of journal citation impact, denoted as source normalized impact per paper (SNIP). It measures a journal’s contextual citation impact, taking into account characteristics of its properly defined subject field, especially the frequency at which authors cite other papers in their reference lists, the rapidity of maturing of citation impact, and the extent to which a database used for the assessment covers the field’s literature.
