Abstract

Introduction: Scientific communication in its new model of performance, enabling access to information in an open way, has contributed so that society can resort to scientific production in an easier way, which has occurred due to its availability in open access journals and institutional repositories. The retrieval of information, in a scientific context, provides access to the intellectual production from the possibility of its search in retrieval systems. Objective: To analyze the information retrieval systems (IRS) based on the search tools of the Brazilian institutional repositories of theses and dissertations available in the BDTD and its databases, comparing them with the parameters established by IBICT. Methodology: Conducts bibliographic research on the theme, documentary research from access to the standards, guidelines and manuals provided by IBICT and case study from the analysis of the retrieval systems of the bases of the repositories linked to BDTD.  Results: It confirms that the institutions participating in the BDTD do not necessarily need to stick to the standards in a partial way established by IBICT, being necessary only that they assign to their repositories the mandatory metadata standards, along with the use of the OAI-PMH protocol and the use of XML technology so that the collection of data occurs for availability in the national BDTD portal. Conclusion: the information retrieval systems of the repositories have technological tools and specifications that confer navigation in the systems by the users, contributing to the best search experience and access to information relevant to the informational issues of the same.
