CIAOColumbia International Affairs Online (CIAO) is designed to be "a comprehensive source for theory and research in international affairs." CIAO provides access to a broad range of scholarly materials published from 1991 onwards, including "working papers from university research institutes, occasional papers series from NGOs [non-governmental organizations], foundation-funded research projects, proceedings from conferences, books, journals, and policy briefs." Maps, country data, topical course-packs, case studies, and a schedule of events and conferences are also available on this site, as is a monthly update service for new content.
