This section of the 4th 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 1977. The available data is arranged alphabetically by country. Information was collected on universities and colleges, institutes and research centers, associations and societies, journals, and publishers, but not all categories were relevant in all countries. Information for the U.S. and Canada was published separately in the Directory of American Philosophers.
