CIES-IUL has several publishing activities whose main aim is to spread the scientific work both of its own researchers and those who collaborate with the centre's members or activities, and also relevant and high quality scientific work developed in the field of social sciences from authors from other research and educational institutions.
CIES-IUL started publishing with the journal Sociologia, Problemas e Práticas (Sociology, Problems and Practices), in 1986. In 2002, with a goal towards internationalization, it launches the periodical Portuguese Journal of Social Science. In 2005, it established the series CIES e-Working Papers, published as open access papers in an electronic format and, in 2010, it launched the publishing house Mundos Sociais. Each of these publications has its own editorial council.
