An impact factor(IF) has been used extensively as a measure of the importance and impact of journals recently. The IF
provided by the Journal Citation Reports (JCR) is calculated based on the most recent three years period. For example, the IF of 2003 for a journal is calculated; the number articles published in 2001 to 2002 cited in tracked journals during 2003 divided by the number of articles published in 2001 to 2002. In this work, we examine the
different patterns of IF of journals in different fields as well as within the same field. We also provide a method of clustering journals according to the characteristics of the corresponding IF within the same field. Based on the experiences from analyzing the IF, we propose modified IFs from statistics point of view as possible new measures for the characteristics of different journals.
