espanolEn la ultima edicion de Google Scholar Metrics (2012-2016) se detecto una brusca caida del numero de revistas cientificas espanolas indizadas. Su numero paso de 1.101 en la edicion 2011-2015 a 599 en la actual. Se realiza un analisis por disciplinas para comprobar cuales han sido las mas afectadas. Despues de repasar varias hipotesis que puedan explicar este descenso, se concluye que ha sido la desaparicion subita de Dialnet en Google Scholar la responsable del incidente. Dado que Dialnet es, en muchos casos, el unico lugar donde se puede encontrar informacion sobre un gran numero de revistas espanolas que carecian de exposicion directa en la web academica, su eclipse ha implicado directamente la invisibilidad de todas estas revistas espanolas que venian siendo indizadas en Google Scholar Metrics. EnglishIn the most recent edition of Google Scholar Metrics (2012-2016) there was an abrupt drop in the number of Spanish scientific journals; the total was 1,101 in the 2011-2015 edition but fell to 599 in the 2012-2016 edition. We conducted an analysis by discipline in order to find which journals were affected. After considering several hypotheses to explain this phenomenon, we conclude the main cause was the sudden disappearance of the Spanish bibliographic database Dialnet from Google Scholar. Because Dialnet is the only online source that provides information about an important number of Spanish journals (which do not have any other online exposure), being dropped by Google Scholar meant that all these Spanish journals, which had previously been indexed in Google Scholar Metrics, became suddenly invisible.
