A description and analysis of the theoretical foundations and methodological procedures in the development of an interdisciplinary corpus, defined/described as “a group of related interdisciplinary categories and similar meanings, recognized by two or more Sciences”, the article presents results of research between Information Science and Administrative Science, based on information and information management. The stages of its development include the theoretical referential that surrounds the interdisciplinarity of the studied areas, especially Heckhausen: documental research for the identification of the authors of Information Science and Administrative Science, identified via Curriculum Lattes and Research Group Directory in CNPq, and foreign authors via Google. Through citation analysis and content analysis of selected Brazilian journals about Information Science and Administrative Science and also, the identification of the concepts found in articles, it was possible to group the interdisciplinary corpus. This methodology can be widely applied and may be adopted in similar research regarding interdisciplinarity in other fields of knowledge.
