The Digital Object Identifier, abbreviated as DOI and emerged in 1997, is a unique alphanumeric string that identifies electronic content and provides a permanent link to its location on the Internet. Twenty-five years after the implementation of this tool, there are still many journals with a considerable impact which do not have DOIs. Cuba does not have it because it is denied by the big registration agencies. The objective of this article was to highlight the importance of the DOI as a basic tool for the control of digital documentation. We concluded that its main contribution is to ensure the persistent and unique identification of a document, through a central systematic record of its metadata. It is recommended that whenever the DOI is available online, it is used in the bibliographic citation, to improve the visibility of the journals and the researchers themselves.
