MEDLINE is the U.S. National Library of Medicine (NLM) premier bibliographic database. It contains references to journal articles in life sciences with a concentration on biomedicine and health. This is broadly defined to encompass those areas of the life sciences, behavioral sciences, chemical sciences, and bioengineering needed by health professionals and others engaged in basic research and clinical care, public health, health policy development, or related educational activities.

MEDLINE also covers life sciences vital to biomedical practitioners, researchers, and educators, including aspects of biology, environmental science, marine biology, plant and animal science as well as biophysics and chemistry.

A distinctive feature of MEDLINE is that the documents are indexed with NLM Medical Subject Headings (MeSH®). ProQuest Dialog™ provides an interactive thesaurus so searchers can take full advantage of these and easily find the right terms for subjects while viewing their broader and narrower hierarchies, subheadings and scope notes.

The greater part of MEDLINE consists of fully indexed documents, but there are also several types of ‘in process’ documents, including those known as ‘Publisher’ documents, which are early-release, electronic versions posted to the web before full bibliographic information is known.

MEDLINE covers virtually every area in the broad field of biomedicine, including, but not limited to, the following:

Clinical Medicine
Population and Reproductive Biology
Pharmacology and Pharmaceutics
Psychiatry and Psychology
Environmental, Public and Occupational Health
Veterinary Medicine
Anatomy and Physiology

Use MEDLINE to answer such questions as:
• What is the latest progress in developing a vaccine for the zika virus?
• Have any clinical trials been conducted on belatacept in kidney transplantation?
• Are there any systematic reviews on the treatment of large non-pedunculated colorectal polyps?
• What are the adverse effects of indomethacin?
