Q. What are some authoritative free medical resources?

For a librarian-curated list of free health sciences mobile apps, websites, health statistics, and clinical information tools, see the Health Sciences Free Resources Research Guide. For consumer health information, we suggest MedlinePlus, a free website for patients and their families from the National Institutes of Health (NIH) and the National Library of Medicine (NLM) that includes trustworthy plain-language health information in English and Spanish.
