The National Health Information Center (NHIC) was created by the Office of Disease Prevention and Health Promotion at the U.S. Department of Health and Human Services in 1979. A primary NHIC service is the Health Information Resource Database which "includes 1,400 organizations and government offices that provide health information upon request. Entries include contact information, short abstracts, and information about publication and services the organizations provide." Site visitors can link to the Resource Database search engine with fields for Title, Keyword, City, and State. Visitors can also locate organizations by linking to an extensive, alphabetic keyword list with subject categories for Arthritis, Child Care, HIV, Nutrition, Public Health, and many more.
