The situation of many indigenous cultures in Australia, North, Central, and South America can be described as one of marginalization or minorization. Subject representation of Indigenous knowledge constitutes one of the contemporary crossroads since, through it, the predominant mentalities of classificationists, classifiers, and indexers are revealed, and this can consolidate hegemonic visions or propose appropriate alternatives to the cultural particularities of Indigenous peoples. From a critical perspective, this work aims to contribute to the systematization of the growing literature on indigenous warrant in KO. The methodology offers quantitative and qualitative data as results of the application of six categories of analysis. The most significant scientific production on the Indigenous issue in KO has come from Canada, the United States, and Australia since 1971. In Latin America, publications only began in 2023, particularly in Brazil. We identified two possible paths to improve the subject representation of the area: adaptation of pre-existing schemes or the creation of new knowledge organization systems specialized in Indigenous culture. Cultural hospitality and indigenous warrant are two relevant tools to guide solutions to improve the subject representation of native cultures. Among other conclusions, from the KO, progress was made in the hierarchy of indigenous knowledge, and there was a need for these cultures to impose their ways of categorizing, naming, and relating things. The urgency of promoting academic production on the subject in Latin America is highlighted, considering the historical and contemporary dimension of its great indigenous civilizations throughout its territory.
