For the researcher seeking European Union developments, a lack of harmonization among members regarding sovereignty and the fact that the United Kingdom, Denmark, and Sweden have not joined the Eurozone means that such searching can be difficult. An example might be, for instance, researching an EU-wide matter or one that requires individual country research. The several ways to stay current with European Union affairs and policies highlighted are EUROPA, EU press releases, international newspapers and news alerts, general EU news, specific EU topics, and the site of the University of Zaragoza in Spain, which is an excellent site for monitoring issues related to the European Union Constitution. The new Health-EU Portal also has very useful information for those concentrating on health in the EU and those who want to monitor and stay current on decisions made at the European Union, national, and international levels. An alternative general news site of use is Statewatch, which is a site for monitoring the state and civil liberties in Europe. As of January 1, 2007, the 27 member countries of the European Union were Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the United Kingdom.
