Impact Factors for 2011 now in Journal Citation Reports
The Impact Facors for 2011 for journals in the Journal Citation Reports were released by Thomson Reuters a few days ago. This years list contains 10 677 journals from 2 552 publishers.
Interestingly, 51 journals have been excluded because of anomalous citation patterns. Likely, the journals contain unreasonable high proportion of self-citations. These journals will be reviewed by the JCR. The fact that such journals can be identified is very important and gives credibility to the system.
It is possible to search out specific journals in the JCR. Also journals within a subject area, a geographic area or from a particular publisher are searchable. The guide below shows how to find impact factors in the JCR.
