A considerable part of the epistemological studies in the field of Information Science, in Brazil, bears on a vector interdisciplinarity. However, some cases betray the difficulties of disciplinary integration and epistemological consolidation. These are based on construction of bibliometric indicators, excluding the discourse functions that reflect the sense effects arising there from. The objective of this paper is to understand the implicit and latent effects in the constitution of this discourse and the potential epistemological barriers to the consolidation of Information Science. The analytical corpus is based on 12 articles selected from the scientific Brazilian production which discuss the disciplinary integration in Information Science. Selection of the articles was based on an analysis developed in a previous phase of this research, seeking the construction of its object and discursive processes. The analysis and discussions were based on discourse analysis of French tradition. The discourse of interdisciplinarity, in information science, is permeated by more than one discursive formation, but is anchored by the dominant discourse which has as its vector the determinations of the informational development mode. This discourse uses naturalizing and generalizing strategies to mask its ideological contour. The fragility in the processes of disciplinary integration translates itself into a difficulty in the epistemological establishment and consolidation of Information Science.
