Created in 2016, JIMIS (ISSN: 2430-3038) is a new international peer-reviewed journal in English or French: « Journal of Interdisciplinary Methodologies and Issues in Science ». It is original because it covers cross-disciplinary topics and issues. Firstly, the editors of a volume propose a topic common to several disciplines. It may be a methodological issue or a thematic area. Authors are then invited to submit articles in English or French, that offer a particular methodological or epistemological point of view on the issue, related to their skills and discipline. How did the authors solve the problem? What methods were used? What is the philosophical position of their proposition? JIMIS much appreciates articles which break away from author's own scientific approaches and put the results obtained in a critical scientific perspective. From confrontation of ideas emerges knowledge.
