The paper analyzes, in a diachronic perspective, the sociological scientific production of Sapienza University. The type and languages of publication, and the co-authorship phenomenon are examined from 2004 to 2014, assuming that the implementation of the policies of evaluation of research ("VTR", "VQR") and regulatory changes on careers (comparative evaluations known as "ASN") had an effect on the characteristics of the scientific production. The explorative analysis here presented, with all the limitations of a case study, shows (through the data extracted from the scientific production repository used by this University) different trends of changes in the characteristics of the contributions and in the different ways of publishing, in the decade 2004-2014. The results provide an interesting framework on sociological scientific production and - in relation to the implementation of the evaluation policies - evidence on the effects that the evaluation processes are producing on scientific communication.
