We proposed a review of the literature on Information Science about the notions of system noted by Bertalanffy and by Luhmann, as way of supporting our understanding about the articulation required between memory institutions and memory systems for the dissemination of information. The objective of this work, therefore was to contemplate, by means of content analysis that which the theorists mentioned here have in recent years, considered about the possibilities offered by the memory institutions in the sense that by acting together, they become memorial systems. As results found from our discussions, we consider the notion of memorial system applied to the memory institutions, thought of as Units of Information, have contributed in the sense of integrating these places of memory around the common good, for social development, making it possible, by means of access to information and collective responsibilities to present ourselves as good ancestors. The methodological procedure used was content analysis.
