Avances del CESOR ratifies the Open Access model in which the contents of scientific publications are fully available for free on the Internet, without temporary embargoes, and whose publishing costs are not transferred to the authors. This policy aims to break the economic barriers that generate inequities in access to information, and publication of research results.

Authors retain the copyrights of their papers and grant the journal right of first publication with the work simultaneously licensed under a Creative Commons that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.
