| Summary: | Objective. This study makes a brief reflection on the preservation of digital records, highlighting the relationship between institutional policies, digital preservation strategies, and computerized systems of management and preservation.
Method. It consists of the lifting of bibliographic material previously published in the areas of Archival Science and Information Science, resulting in an unsystematic review article. Consulted sources consist of books, theses, texts on websites and scientific journal articles indexed in Google Scholar, with a time frame for the last twenty years.
Results. The literature leads to the need to define in advance the policies of digital preservation, and after, implementing computerized systems for management and preservation, maintaining high levels of interoperability. In addition, it is noted the issue of keeping an unbroken chain of custody covering the three ages of the document life cycle.
Conclusions. This study synthesizes aspects of a digital preservation system basically managed in two distinct stages, but interoperable. This reinforces the discussions on the chain of documentary custody and interoperability between standards, computerized systems and other software used in the collection.
