The article analyses the main characteristics of scientific production in the communication sciences by Catalan authors during the years 20072009. Bibliometric techniques were used to observe institutional productivity, publication patterns, collaboration dynamics (intra- and inter-institutional) and journal consumption. The study is based on articles by authors attached to Catalan universities, companies and institutions and published in any of the sixteen main Spanish communication journals or in publications listed in the communication section of the Social Sciences Citation Index. Results reveal two different patterns of behaviour, depending on whether a Catalan researcher publishes in a Spanish or international journal.
