Open Access is increasingly a determining part of the structures and processes of scholarly communication, particularly in the emerging open science modus operandi, which presupposes the opening of all research components. Currently, most scholarly communication instances, products and services refer to open access in some way. The bibliographic indexes started to identify open access articles. New publishers were created, most commercial publishers started to publish open access journals or offer authors the possibility to publish open access articles in subscription journals. Open access mega journals have appeared. In developing countries, open access journals predominate, with emphasis on the pioneering SciELO Program, publishing open access journals from 1998, four years before the Budapest Open Access Initiative declaration. The preprints modality with open access availability of manuscripts before evaluation and publication in journals grows and new tools appear. Several innovative models have emerged in recent years to promote open access to journal articles, such as library consortia or crowdfunding. There is still difficulty and resistance from publishers in developing financial models that enable open access, and the calculation of article processing charges (APC) remains opaque. But the main force that can make the universalization of open access viable is public policies, the best example being currently the European Commission’s Horizon 2020 program. Before this landscape, this panel will analyze progress already achieved, the promising solutions and the persistent barriers in the routes towards the universalization of open access. Syllabus The classical open access modalities – gold route journals, green route, new models of open access financing, metrics on the status of open access, barriers to the universalization of open access, and open access policies.
