The Cochrane Library
The Cochrane Library consists of a regularly updated collection of evidence-based databases, including thousands of Cochrane Reviews published in The Cochrane Database of Systematic Reviews. (More about the Cochrane Database of Systematic Reviews is available here.)
These reviews explore the evidence for and against the effectiveness and appropriateness of treatments (medications, surgery, education, etc) in specific circumstances. The Cochrane Library is published monthly by Wiley Online Library. Details on the current number of available Cochrane Reviews and the Impact Factor, please click here.
