An excellent place to start researching the crisis in Europe with the default worries, how they affect the Euro currancy and so on would be in Business Source Complete. This business and economics article database is perfect for finding articles from business and economics journals, magazines, and newspapers. (Except for the Wall St. Journal, which we have in a separate database.) Lexis has a great newspaper collection, including many foreign newspapers in English language versions.
Our Research Guide to Business and Economics can suggest many more resources, for example it has links in the Statistical section to databases like EuroStat, a rich source of financial and other statistics on the European Union and its member countries.
