Europa is the main gateway for European Union information. It includes a glossary of European Union terms, the EU Bookshop, which includes many free publications on European Union policy issues, press releases, and links to legislation and treaty documents. Europa hosts Com Documents, or Commission Documents from the European Commission, which include legislative proposals, “white papers” and other documents pertaining to recent policy issues, as well as Summaries of EU Legislation. Activities of the European Union provides overviews of several policy areas, and commission proposals can be monitored using the Pre-Lex database.
