An important piece when researching global management is understanding the history, culture, and policies of another country. Country reports are a valuable resource for discovering this information:
globalEdge Global Insights: International business and trade information on over 200 countries, nearly 2 dozen industry sectors, and many of the world's trade blocs.
UNESCO Institute for Statistics, Regional and Country Profiles: Profiles include statistics regarding education; literacy; science, technology and innovation; and culture.
World Bank Open Data: Free and open access to data about development in countries around the globe.
Many industry reports provide global insights.
Journal articles provide you with scholarly insight on a problem or trend. These two databases offer a lot of business/management content, much of it full text. They are a good place to begin your search for journal articles.
