This section of the 3rd edition contains listings for philosophy-related institutions and journals in Africa, Asia, Australia, Europe, and Latin America. Most of this information was collected from questionnaires completed and returned throughout 1973. The available data is arranged alphabetically by country. Information was collected on universities and colleges, institutes and research centers, societies and associations, journals, and publishers. Listings for each country only contain the information available to the editorial office. Information for the U.S. and Canada was published separately in the Directory of American Philosophers.
