The aim of this work is to establish a model by applying evaluation indicators to the quality of bibliographic references in scientific works. 5 quality indicators are developed for the bibliographic review in the body of the work and 9 for the bibliographic references (bibliography) included at the end. The indicators were developed using the structure recommended by the ISO 11620 standard. An observation guide is also presented to be used, in order to collect and weigh the information from the bibliographic references. The proposed model constitutes a proposal open to new reviews, contributions and / or suggestions.
