This white paper (WP) written by the OPERAS Special Interest Group Multilingualism aims to answer: Objectives: Given the growing need to strengthen the bonds between stakeholders involved in scholarly communication and multilingualism, this WP has a three-fold purpose: (i) synthesize evidence in the literature as to innovative dynamics of knowledge-sharing and scholarly communication within linguistically diverse scholarly contexts and research networks; (ii) have a better understanding of the role of multilingualism within bibliodiversity in scholarly communication, through the lens of publishers and translators/researchers; and (iii) present the conceptual design of a future OPERAS Translation Platform aiming at supporting translation services at the scholarly communication level (involving publishers, translators, researchers). Goals: to prepare theoretical background to discuss the usage of multilingualism in scholarly communication to identify, analyse, and understand innovative dynamics of working practices and knowledge-sharing within linguistically diverse scholarly contexts and research networks to identify and analyse the motivations behind these practices (questionnaires/focus groups - how tools may answer to needs) to formulate recommendations/guidelines for OPERAS regarding the future implementation of a service aiming at enhancing multilingualism to prepare the conceptual design of a platform prototype for shared translation service at the scholarly communication level (involving publishers, translators, researchers).
