  1. * Institute for Scientific Information or Social Science Citation Index Journal Citation Reports, 1999. Impact factor is a measure of the frequency with which the "average article" in a journal has been cited in a particular year, calculated by dividing the number of current citations to articles published in the two pervious years by the total number of articles published in the two previous years. Immediacy Index is a measure of how quickly the "average article" in a journal is cited, calculated by dividing the number of citations to articles published in a given year by the number of articles published in that year. Higher values indicate higher impact. † Current circulation obtained from Ulrich's International Periodicals Directory, 39th Edition, 2001 and/or confirmed by communication with publisher.
