Regional health and medical databases have been compiled to complement the internationally known bibliographical indexes such as MEDLINE from the US National Library of Medicine. The Regional medical indexes, published by or under the auspices of WHO Regional Offices give access to bibliographical information about the health material published locally. They thus add a further dimension to the retrieval of information from developed country-oriented database. A collection of health and biomedical databases covering the following regions is available: Africa, Eastern Mediterranean, South-East Asia, Latin America and the Carribean (languages: Portuguese, Spanish and English), and Western Pacific. Each regional database includes resources that are not easily found elsewhere, as well as international journals.
