The European Commission compiled a list of the 22 universities in the EU with the highest scientific impact. This ranking was compiled as part of the Third European Report on Science & Technology Indicators, prepared by the Directorate General for Science and Research of the European Commission in 2003 (updated 2004). It only explicitly considers the European Union's top institutions, but comparisons with the rest of the world are provided in the full report. The report says, "University College London comes out on top in both publications (the number of scientific publications produced by the university) and citations (the number of times those scientific publications are cited by other researchers)" however the table lists the top scoring university as "Univ London" implying that the authors counted the scientific output of the entire University of London, rather than its constituent colleges.
