Google Scholar Metrics 2013: nothing new under the sun

Abstract: Main characteristics of Google Scholar Metrics new version (july 2013) are presented. We outline the novelties and the weaknesses detected after a first analysis. As main conclusion, we remark the lack of new functionalities with respect to last editions, as the only modification is the update of the timeframe (2008-2012). Hence, problems pointed out in our last reviews still remain active. Finally, it seems Google Scholar Metrics will be updated in a yearly basis
