New impact factor for Cochrane Database of Systematic Reviews – great news!

The ISI Journal Citation Report came out today, with all new journal impact factors for 2010.  The impact factor is a tool for ranking, evaluating, and comparing journals. It is a measure of the frequency with which the “average article” in a journal has been cited in a particular year. It is calculated by looking at the number of citations as a proportion of articles in the journal published in the previous two years and is a measure of the importance of a journal or journal article to research.

The great news is that the Cochrane Database of Systematic Reviews (part of the Cochrane Library) has received an impact factor of 6.186. This puts it in the top ten of Medicine (General and Internal) journals in the world, and means that the impact factor has increased for the 4th year in a row.

The total number of times the CDSR was cited increased from 23,102 in 2009 to 27,366 meaning the CDSR receives the 7th  highest number of citations in its category.

Congratulations to all our authors and contributors whose hard work has been instrumental in this fantastic achievement.
