The 2014 Journal Impact Factors are now available via Journal Citation Reports. These are the most recent Impact Factors. The 2015 metrics will become available in the summer of 2016. Journal Impact Factors are a proprietary measurement of journal quality based on the number of citations publications appearing in that journal have received in the last two publication years. Impact Factors are available for some 7000 journals across many fields and are published annually.
Impact Factors can be viewed through the Journal Citation Reports database available through WHSC Library subscriptions.
