The Mayo Clinic has partnered with Oxford University Press to publish a line of medical reference titles and textbooks. OUP is looking to release seven to ten titles annually under the Mayo Clinic Science Press, as it will be called, all written by Mayo Clinic doctors and/or researchers. The first title in the series is slated to be released in February 2010. The well-regarded Mayo Clinic, which is the largest not-for-profit group medical practice in the world, has three hospitals, in Minnesota, Florida and Arizona.
