H Index Communication Journals according to Google Scholar Metrics (2008-2012)

The aim of this report is to present a ranking of Communication journals covered in Google Scholar Metrics for the period 2008-2012. It corresponds to the H Index update made last year for the period 2007-2011 (Delgado L\'opez-C\'ozar and Repiso 2013). Google Scholar Metrics doesnt currently allow to group and sort all journals belonging to a scientific discipline. In the case of Communication, in the ten listings displayed by GSM we can only locate 46 journals. Therefore, in an attempt to overcome this limitation, we have used the diversity of search procedures allowed by GSM to identify the greatest number of scientific journals of Communication with H Index calculated by this bibliometric tool. The result is a ranking of 354 communication journals sorted by the same H Index, and mean as discriminating value. Journals are also grouped by quartiles.
