What is IRIS? IRIS is our research information system and serves as the institutional repository for UNIL publications. The referencing and deposit of a version of scientific publications produced as part of research at UNIL is mandatory for the entire UNIL research community. Since IRIS is harvested by major search engines, it is a very useful tool for increasing the visibility of the institution's scientific output and its researchers. It has a dual purpose: On one hand, it enables long-term archiving of the institution's scientific output. On the other hand, it maximises researcher visibility, in particular by enabling publication via the Green route (Green Open Access).
