The Journal Citation Reports (JCR) is part of the Web of Science and provides quantitative tools for ranking, evaluating, categorizing, and comparing journals. The impact factor measures the frequency with which the "average article" in a journal has been cited in a particular year or period. The annual JCR impact factor is a ratio between citations and recent citable items published. Thus, the impact factor of a journal is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years (see Figure 1). Only journals included in Web of Science are used for the calculation.
|Figure 1: Calculation for journal impact factor.|
|A= total cites in 1992|
|B= 1992 cites to articles published in 1990-91 (this is a subset of A)|
|C= number of articles published in 1990-91|
|D= B/C = 1992 impact factor|

The tutorial on Browsing and analyzing journals explains how to use the Scopus Journal Analyzer tool to compare publications on a variety of parameters. You will also learn how to find information about specific journals.
HOW TO FIND THE IMPACT FACTOR:
1) Use the Journal Citation Reports feature of Web of Science (at Rutgers). Look up an individual journal title, or find a journal in a list by subject category.
2) Find the journal website and look on the About page for the impact factor.
3) Contact your librarian who may already have the list you seek.
