This paper aims at presenting a case study that analyzed the role of the librarian in the implementation of an institutional repository (RI) in the Funda o Centro Tecnológico de Minas Gerais (CETEC). The implementation of the RI in CETEC has become necessary in order to organize systematically and effectively the scientific production of that institution. It was verified that is necessary for the librarian be adaptive to the new information tools and know how to use the emerging technology. To achieve these goals, many disciplines related to information technology could be inserted in the course curriculum of librarianship in Brazil in order to support the librarian to be more autonomous in dealing with the software and to optimize his/her work. Finally, in general, it is important that the librarian encourages the creation and implementation of RIs and be aware to the movement for open access to information.
