title: [The knowledge diffusion as an educational tool].
abstract: To disseminate knowledge, several instruments have been used, among them periodicals. Since the 1960s, the impact factor has been used to rate the importance of journals, and simultaneously, the work of researchers. In this paper we propose to evaluate journals, in addition to the impact factor, through their circulation, readership size, print runs, and internet access.
