The Observatoire des sciences et des technologies (OST) (Vincent Larivière, Université de Montréal and Université du Québec à Montréal) is developing a citation index that will be integrated to the Érudit platform and that is based on its corpus of scholarly journals. This index records bibliographic references found in publications in order to draw citation networks connecting the documents together. The index is also available as a bibliometric database for researchers interested in the production and the dissemination of knowledge.
