Which journals in my area have the highest impact?
Journal titles are assigned to one or more subject categories in the JCR. This means a journal can be ranked differently depending on the category being reviewed. Differences also occur between resources. The following list highlights this issue in relation to three journal titles.
- Title: Plant Biosystems Ranking in JCR/WoS: 120/156 in Plant Sciences Ranking in Scopus/SciMap: 90/291 in Plant Science
- Title: Waste Management Ranking in JCR/WoS: 7/38 in Engineering, Environmental, 44/163 in Environmental Sciences Ranking in Scopus/SciMap: 1/92 in Geotechnical Engineering and Engineering Geology
- Title: Ecological Economics Ranking in JCR/WoS: 19/209 in Economics (Social Sciences Edition), 6/58 in Environmental Studies (Social Sciences edition), 53/124 in Ecology (Sciences edition), 60/163 in Environmental Sciences (Sciences edition) Ranking in Scopus/SciMap: 63/157 in Ecology, Evolution, Behavior and Systematics
Citation practices can vary significantly from one field to another. For example, articles in biochemistry often contain over fifty cited references, while a typical mathematical paper has perhaps only ten. This difference explains why biochemical papers are cited so much more often than mathematical ones. The traditional impact factor cannot therefore be used to compare journals across different subject areas. SNIP is an advanced citation indicator that corrects for such differences.
This list of journal titles and JCR impact factors from 2009 highlights discipline differences:
- American historial review - 2.114
- Review of educational research - 3.326
- Annals of mathematics - 4.174
- Journal of economic literature - 6.919
- Nature photonics - 22.869
- Annual review of immunology - 37.902
- New England journal of medicine - 47.050
These journals all have the highest impact factor in their category.
