Journal rankings are often used to identify the top research journals in a field.
We have updated the FAQ answer:
Where can I find a ranking and rating of business and management journals?
to make the distinction between general rankings and those specific to business and managment clearer.
Journal ranking is not perfect and there is significant research into its effectiveness. For example, the Journal Citation Report (JCR) rankings are strict in terms of the journals covered (with natural and life sciences better covered than social sciences) so journal focussed on new emerging areas do not score well.
