The objective in this paper is to summarize the current knowledge that is available for Discovery Tools that have been employed for library services and open access repositories (OAR); This mapping is intended for studies which have addressed the concept and application of these, identify studies that have applied the Discovery tool to the context of the OAR and whether its implementation has benefited to the scientific visibility. The results of this study will measure the implications that we will have to consider to implement a Discovery Tool in a repository that will provide visibility to the results of the project "Binational Laboratory for the Intelligent Management of the Energy Sustainability and the Technological Formation" and to generate a prototype to evaluate and to measure the experience of the involved users for users looking for information on open access technological platforms with discovery tools.
