The impact factor (IF) of an academic journal is a measure reflecting the average number of citations to recent articles published in that journal. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones. The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information. Impact factors are calculated yearly starting from 1975 for those journals that are indexed in the Journal Citation Reports.
In any given year, the impact factor of a journal is the average number of citations received per paper published in that journal during the two preceding years. For example, if a journal has an impact factor of 3 in 2008, then its papers published in 2006 and 2007 received 3 citations each on average in 2008. The 2008 impact factor of a journal would be calculated as follows:
where:
(Note that 2008 impact factors are actually published in 2009; they cannot be calculated until all of the 2008 publications have been processed by the indexing agency.)

Impact Factor is a seminar series where we will explore what research universities do… for example, what’s expected of their faculty, what sort of changes we could expect if we became a research university, and so forth. How far can assistant and associate professors at Texas State University, who want to be tenured and advance in rank; how far can they go when they publish in non-traditional venues? How much risk can an assistant or associate professor assume if he or she wants to reach wider audiences than just the audiences of narrowly focused and highly technical academic journals? When does non-traditional publishing push the bounds of what’s acceptable in an academic, tenure-driven environment? Find out in this episode. What would Texas State be like if it became a research univer...
