Preservação digital

Abstract: The aim of this article is to provide a broad and reflective perspective on the main aspects of digital preservation, based on the challenges indicated, the recognized requirements and the strategies analyzed by the scientific community. The methodology adopts quantitative-qualitative and exploratory-descriptive research, with a review of the national and international literature of the last twenty-one years on digital preservation, in order to delineate the trends and policies on the theme as well as deepening the discussion on the needs for archiving and long-term preservation of digital content. Data is analyzed from the bibliographic survey of scientific publications indexed by Scopus and Web of Science from the last five years (2015-2019) that deal with the subject “digital preservation”. It was found that among the themes discussed, budgets, costs and metadata for preserving and Web archiving are emerging and studies lacking in Brazilian Information Science. In the international scientific output, Brazil stands out for publication quantity, indicating a maturation of the theme, coinciding with the advance of national projects, such as the Cariniana Network. However, we have financial, human and technological demands that, together with the characteristics of strategies for digital preservation, highlight the usefulness of collaborations and of little-explored national topics.
