LETRINT-Q is a corpus query interface that enables users to explore the LETRINT 1 and the LETRINT 1+ corpora. It was developed for the LETRINT project ("Legal Translation in International Institutional Settings: Scope, Strategies and Quality Markers", Consolidator Grant 157797) on the basis of the corpus-querying application ParaVoz. Although LETRINT-Q is an open-source tool, prospective users are kindly asked to fill in the following form in order to obtain the access credentials. This enables us to keep track of the platform uses and to better process feedback about its functionalities.
