Also, Google is your friend when searching for specific data series. For general searching, keep it simple - a country, topic, and "statistics" works well (e.g. "China Export Statistics" as your search term). Print statistical reports and subscription statistical databases may be located by searching in the Library Catalog for "Statistics" and a subject term.
