Revistas científicas de ciências da comunica？？o em Portugal: da divulga？？o do conhecimento à afirma？？o do Português como língua de pensamento

the first scientific journals of communication sciences in portugal appeared in the mid-1980s. today, although the editorial initiative has been diversified and extended from lisbon to other universities, the paper publications do not reach even a dozen. to these are added some journals exclusively online, which have contributed to expand the scope of the thematic focuses. within this paper, we tried to make an inventory of journals that are published in portugal, at the same time reflecting on their main weaknesses: the lack of rigour in periodicity in some cases and in others the tendency to publish texts in ？？other languages than portuguese only. it is also objective of this study to support the importance of registering these publications in the most relevant international index, and to assert the research carried out in portugal, as well as to promote the portuguese as a language of thought.
