The science of medicine falls into two general categories, preclinical research and clinical research. Research that is designed to increase knowledge for the development of new treatments is classified as preclinical. Research that evaluates the safety and efficacy of new treatments is considered clinical research. Funding for a large portion of medical research comes from the U.S. federal government via the National Institutes of Health (NIH) and information gleaned from this research is collected by the National Library of Medicine (NLM). However, a number of other federal agencies also participate in medical research.
