Which journals in my area have the highest impact?

Subject categorisation

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 table highlights this issue in relation to three journal titles.

Source title Ranking in JCR/WOS Ranking in Scopus/SciMap
Plant Biosystems 120/156 in Plant Sciences 90/291 in Plant Science
Waste Management 7/38 in Engineering, Environmental
44/163 in Environmental Sciences
1/92 in Geotechnical Engineering and Engineering Geology
Ecological Economics 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)
63/157 in Ecology, Evolution, Behavior and Systematics

Discipline differences

Citation practices can vary significantly from one field to another. For example, articles in biochemistry often contain over 50 cited references, while a typical mathematical paper has perhaps only 10. 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 (see 3.3) is an advanced citation indicator that corrects for such differences.

Discipline differences are highlighted in the following table:

Source title JCR impact factor 2009
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.
