World’s premier medical/health science database Articles from all health fields: medicine, nursing, dentistry, exercise science, veterinary medicine, allied health, etc. 4800 journals Over 19 million citations back to 1940
We now have a “meta” search engine that searches CINAHL, Medline and our other databases at once. It is on the library homepage and it’s called the “search all” box
