In August 2006, the American magazine "Newsweek" published a ranking of the Top 100 Global Universities, using selected criteria from ARWU and the Times Higher Education-QS rankings, with the additional criterion of the number of volumes in the library. It formed part of a special issue including an article from Tony Blair, then prime minister of the UK, but has not been repeated. It considered openness and diversity as well as distinction in research. The ranking has been continued since its merger with The Daily Beast, and currently uses data from the Times Higher Education World Rankings, Webometrics world college rankings from public-research outlet Consejo Superior de Investigaciones Científicas in Spain, and the Shanghai Ranking Consultancy in order to compile its results.
