El DOI en las revistas científicas del portal SciELO : DOI in scientific journals of SciELO portal

The research provides a description of the SciELO journals portal and the DOI identifier through its range, year of creation, history, management, policy, structure, ISBN-A and reference sources. It provides information on the implementation of the DOI in citations styles APA and Vancouver, and standards ISO 690-2010 and ABNT6023-2002. The work aimed to explore the degree of implementation of the DOI in scientific journals in SciELO, identify where DOI display, knowing the amount of publishers as DOI prefix, determine the number of journals titles including the ISSN suffix code and identify the degree of implementation of the DOI in the styles and standards of citations available in SciELO. Descriptive methodology was applied where data were collected through direct observation of the websites of the 898 current journals available between the months of December 2012 and January 2013 in SciELO portal. It concludes that there are few countries that are currently using the DOI in its publications, primarily displayed code in HTML files, only 30 publishers implemented it and most include the ISSN identifier within the suffix. While using the DOI in all citations of the articles, not does so strict as the provisions of the rules and styles.
