This is what I love to hear (and I’m sure you’ll agree): The United Nations Common Database is now free! From the site:
As of 1 May 2007, use of the Common Database will be FREE OF CHARGE. No subscription will be necessary after that date, and all users can access the full range of data, metadata and various search tools without restriction.
A new system, UN data, will be launched in Summer 2007 and will provide improved access and searchability for UNSD databases.
