The creation and development of databases of historical newspapers are essential for studying the history of journalism. Several international projects have been dedicated to this purpose, focusing on digitization, availability and access. Often, the control of authority by the subject is not considered. It is striking, in this context, the absence of standardized subject indexing, which does not allow, for this reason, the development of interoperability processes with other databases concerning the search by subject. The control of the vocabulary existing in knowledge organization systems aims to reduce the ambiguity of natural language and contribute to the retrieval of relevant information in the face of a determined information need. This work begins by presenting and critically analyzing some relevant international projects from collections of digitized historical newspapers, explaining the path underlying the technical development of the databases and the various forms of information retrieval. Several possibilities of using knowledge organization systems in the indexing of historical newspapers are presented, showing their applicability also in Portuguese newspapers' collections.
