The Europeana digital library reopened on Tuesday, more than a month after it crashed because of heavy use.
The European Commission says server capacity for the digital library has been quadrupled to handle demand.
The online library that pulled together collections from more than 1,000 institutions, including the British Library and the Louvre, crashed on its first day of operations — Nov. 20.
Its EU backers had failed to anticipate the 10 million hits per hour it experienced on the first day.
The Europeana project allows users to access films, paintings, photographs, sound recordings, maps, manuscripts, newspapers, and documents as well as books kept in European libraries.
