SciELO 20 years: from visionary to indispensable

The SciELO 20-years Conference was held in September 2018 in Brazil. It constitutes an important landmark in SciELO’s evolution. The conference addressed the main political, methodological and technological issues in scholarly communication, and the trends and innovations that are shaping the future of the universal openness of scholarly publishing. A major focus was made on the SciELO network, and why it is indispensable. The presentations were added to the programme. The updated priorities and advances to open science are also refered to.
