The Cybermetrics Lab from CSIC has just published the new July 2010 edition of their Ranking Web of World Universities (http://www.webometrics.info). In this new edition, the coverage of the Asian region has been greatly expanded and the number of higher education institutions analyzed is over 20,000 being offered the ranking of the Top 12,000. North American universities still lead the tables (Harvard, MIT, Stanford and Berkeley are the first four), together with the Canadian institutions behaving very well surpassing the privilege positions of the British ones. In Europe, apart from the mentioned British (Cambridge and Oxford and Edinburgh in Scotland), it is also worth mentioning the rankings of the Swiss (ETH Zurich) and the Nordic ones (Helsinki, Oslo).In more delayed positions appear the universities from Germany, France, Italy or Spain, mostly due to the fact that research in this countries is developed by independent institutions (Max Planck, CNRS, CNR, CSIC). In Latin America the UNAM from Mexico reaches the 70th of the world, being specially remarkable the large number of Brazilian universities, leaded by Sao Paulo, found between the best of the region. Universities of Chile and Buenos Aires are positioned just behind. Universities of Japan, Hong Kong and Singapore lead the Asian ranking, and behind them are the Taiwanese and Korean ones. Chinese universities are still lagging behind their neighbors and the institutions from the Indian subcontinent have delayed ranks. The Ranking Web of World research Centers (http://research.webometrics.info) complements the previous one, with a directory of more than 7,000 entries from which the classification of the Top 4000 is offered. The National Institutes of Health of USA and NASA lead the Ranking, being followed very closely by the French CNRS. The Cybermetrics Lab develops its activities at the Centro de Ciencias Humanas y Sociales of the CSIC in Madrid. Their rankings are being published twice a year (January and July) since 2004 and they pretend to motivate and reinforce the role of the university as a source and distributor of web contents of high quality and open access. -- =========================== Isidro F.
