Based on the background of Information Science in Brazil, during ten years, from 1994 to 2005, of doctorate of the Post-Graduation Program in Information Science according to agreement signed between CNPq/IBICT and UFRJ/ECO, 58 theses were published. The objective of this study is to investigate, through principles and categories, the relation of the different disciplines to information science. The model used divided the corpus of theses into three categories: the first refers to the fact that the disciplies are distinct sets, each one remaining at the surface of the approach, because the concepts and methods of category were not entirely fit for formalizing an interdisciplinary frame.The second category refers to the interaction of the concepts approached with a link of the issues placed by the disciplines seeking solution for the proposed problem. The third category refers to the integration between the discipline and information science, presenting a common language. The conclusion is that the results of this study will be a contribution for the establishment of a method of interdisciplinary research for Brazilian post-graduation.
