OPERAS is a European Research Infrastructure dedicated to advancing open scholarly communication in social sciences and humanities (SSH). Its goal is to achieve an Open Science environment where SSH research benefits society without barriers. OPERAS provides the research community with a missing brick in the scholarly communication system by unlocking resources and enabling SSH to reinvent itself in the new Open Science paradigm. OPERAS offers a comprehensive approach to scholarly communication, supporting the entire cycle of scholarly communication, and enabling greater community control over openness and accessibility. OPERAS aggregates, federates, and scales up resources, providing services to increase the overall quality of SSH research. By unlocking resources, making them FAIR and enabling SSH to reinvent itself in the new Open Science paradigm, OPERAS hopes to support SSH research that benefits society without barriers. Overall, OPERAS offers a range of useful services that can greatly benefit researchers and authors in the humanities and social sciences community. These services enable researchers to discover open scholarly resources, improve the quality of peer-review practices, engage in collaborative citizen science projects, and more. There are three types of services provided by OPERAS: 1.) Services managed by OPERAS, responsible for the overall coordination, delivery, and evolution. 2.) Services managed directly by community providers but discoverable through the OPERAS catalogue. These services are required to have sustainable structures to be established, but receive direct OPERAS participation, contribution, and support. 3.) Services necessary for managing and operating the OPERAS federation, both technical and non-technical. These services across the 3 types can be grouped into seven categories: Discovery, Analytics, Quality Assurance, Research4Society, Training, and Operational and Collaboration Tools. Through its legal entity, the OPERAS AISBL, OPERAS ensures the sustainability and long-term development of its activities and services, as well as the effective collaboration and coordination of its members and partners. The AISBL also enables OPERAS to engage in partnerships and collaborations with other organisations and stakeholders and to represent the interests of the SSH research community at the European and international levels. It is governed by the General Assembly and the Executive Assembly.

Between 2012 and 2014, the need for coordinated actions in SSH digital practices and Open Access for books was recognized in various conferences such as ELPUB, JISC, and OAPEN. During this time, informal contacts and networking were instrumental in shaping the future project OPERAS. From 2015 to 2018, the focus shifted to the design phase. The OPERAS network was established, consisting of a Core Group representing 9 countries and 40 members. Projects like HIRMEOS EINFRA-2016-1 and OPERAS-D INFRASUPP-2016-1 were initiated to develop innovative services for books and design infrastructure, respectively. This period also saw the publication of design studies and white papers, culminating in the first OPERAS conference and an application to ESFRI, which recognized the project's high strategic potential in research. Preparation activities took place between 2019 and 2022. Projects like OPERAS-P (INFRADEV-2019-2) and TRIPLE (INFRAEOSC-2019-2) were launched to address design, business model, and governance issues, as well as to develop a discovery service as building blocks. In 2019, the OPERAS AISBL was established, focusing on service creation and alignment for the EOSC catalogue and transnational access. The implementation phase, spanning from 2023 to 2027, began with the OPERAS-PLUS project in 2021, aiming to ensure an efficient transition to operation with a comprehensive approach to technical, administrative, and financial matters. Projects like DIAMAS, CRAFT-OA, Skills4EOSC, and GraspOS were initiated in 2021 and 2022 to address various aspects of open scholarly communication and enhance collaboration on Open Science issues. Additionally, the adoption of the second OPERAS Strategic Plan (2023-2025) occurred in 2023, alongside the Palomera project focusing on monographs in open access. The ATRIUM project was launched beginning of 2024, collaborating with other SSH ERICs to tackle common services and issues in the perspective of the building of the SSH cluster of the EOSC. Finally, the OPERAS ERIC should be established in 2027. The Research Infrastructure OPERAS, dedicated to open scholarly communication, has profound impacts across various domains. Scientifically, it cultivates collaboration among researchers by facilitating the sharing of data, methodologies, and findings, thus fostering comprehensive studies and interdisciplinary research. Additionally, by promoting open access to research outputs, OPERAS enhances transparency in the scientific process, thereby bolstering the reliability and credibility of scientific knowledge. Moreover, by eliminating barriers to access and reuse of scholarly materials, OPERAS accelerates innovation, fostering the development of new theories, methods, and applications. Economically, OPERAS contributes to cost reduction by eliminating subscription fees, making research outputs freely available to all. This reduction in costs benefits academic institutions, libraries, and individual researchers. Furthermore, OPERAS facilitates knowledge transfer between academia, industry, and society at large. Additionally, by promoting collaboration and innovation, OPERAS creates new job opportunities in research, publishing, data management, and related fields. Societally, OPERAS ensures increased access to knowledge, democratising information and promoting informed decision-making and public engagement with science. Furthermore, by reducing disparities in access to information, OPERAS fosters inclusivity, diversity, and social equity in academia, providing equal opportunities for researchers from diverse backgrounds and geographic locations.
