Europeana

Free

Coming soon to a laptop near you: Vast treasures from more than 1,000 manuscripts, as well as museums, libraries, archives, and film and sound materials from 27 European nations. From the Magna Carta to music scores by Mozart, Europeana seems to be the European Commission's answer to Google's ambitious venture (along with the Library of Congress) to create a World Digital library. The site offers multilingual searching and plans to have ten million items by 2010. A prototype version with two million items went live last November, got swamped by users, promptly crashed, and is now up and running again with quadruple the server capacity. Stay tuned for the full-blown site.
