Europeana Multilingual Collections

German 18% Multilingual 12% French 11% Dutch 10% Swedish 9% Spanish 8% English 7% Norwegian 6% Polish 6% Italian 6% Finnish 3% Danish 2% Hungarian 1% Slovenian 1%

à Most Europeana

  • bjects are language-

independent (e.g. images), but the meta- data is multilingual.

Multilingual Europeana Users

  • Native language browser: 69%
  • Native language Google (entry point): 91%
  • Native language objects: 43% (SV 77%, DE 71%)

à Native language use increases as soon as native language content increases.
