eHRAF World Cultures This link opens in a new windowThe eHRAF World Cultures is an online cross-cultural database containing descriptive information on cultures and ethnic groups from around the world-- unique because each culture contains a variety of full-text source documents (books, articles, and dissertations) that have been indexed and organized according to HRAF's comprehensive culture and subject classification systems: the Outline of World Cultures (OWC), and the Outline of Cultural Materials (OCM). These retrieval systems extend search capability well beyond keyword searching, allowing for precise culture and subject retrieval, even in a foreign language. As a multicultural database, eHRAF appeals to many academic disciplines in the social sciences, humanities, medicine, and any other area with an interest in cultural diversity.
