Introduction: The purpose of vocabulary control is consistency in representation and retrieval in order to avoid the dispersion of informational resources related to the terms of the controlled vocabulary. Digital repositories are currently of fundamental importance in the organization and management of knowledge whose information resources, besides stored and preserved, need to be accessed and retrieved without inconsistencies. For this, it is important to verify the incorporation of types of controlled vocabulary in university repositories in the processes of representation and retrieval. Objective: This research proposes research on controlled vocabularies in repositories with the purpose of verifying search and navigation interface resources to identify the incorporation of types of controlled vocabularies in the representation and retrieval of information. Methodology: Documentary analysis, through electronic research, for the collection of repositories and exploratory research for the analysis of interface resources to identify types of controlled vocabularies used in representation and retrieval of information based on parameters obtained in the theoretical basis. Results: The analysis of the search interfaces of 86 Brazilian repositories revealed that controlled vocabularies were generally incorporated into representation and retrieval for the following types: thesauri (6 repositories), classified lists (8), taxonomies (7), and lists of terms in alphabetical order (70). Metadata includes natural language keywords and vocabulary terms controlled in 56 repositories. Conclusions: Lists of terms in alphabetical order used to search for subjects in navigation interfaces need to incorporate the vocabulary control function by integrating the keywords with the terms of the controlled vocabularies and obtaining consistency in the retrieval.
