JOURNAL IMPACT FACTORS & JOURNAL CITATION REPORTS (JCR)

Journal Impact Factors are generally accepted numbers used for ranking, categorizing, and comparing scholarly journals within an academic discipline. A journal's impact factor is a measure of the frequency with which the "average article" in that journal has been cited within a set period of time. Journals assigned the highest impact factors are perceived to have more influence on the discipline than those journals assigned lower numbers.

The Journal Citation Reports (JCR), published by ISI, may be consulted to determine the annual JCR impact factor for specific journals or the rank of several journals within an academic disciplne. The JCR impact factor is a ratio between total citations and recent citable items published. The assigned number is determined by dividing the number of current year citations by the total applicable items published in that journal during the previous two years.
