National differences in dissemination and use of open access literature

Open Access (OA) dissemination has been gaining a lot of momentum over the last decade, thanks to the implementation of several OA policies by funders and institutions, as well as the development of several new platforms that facilitate the publication of OA content at low or no cost. Studies have shown that nearly half of the contemporary scientific literature could be available online for free. However, few studies have compared the use of OA literature across countries. This study aims to provide a global picture of OA adoption by countries, using two indicators: publications in OA and references made to articles in OA. We find that, on average, low-income countries are publishing and citing OA at the highest rate, while upper middle-income countries and higher-income countries publish and cite OA articles at below world-average rates. These results highlight national differences in OA uptake and suggest that more OA initiatives at the institutional, national, and international levels are needed to support wider adoption of open scholarship.

Open access to scientific publications has progressively become a key issue for European policy makers, resulting in concrete measures by the different country members to promote its development. The aim of paper is, after providing a quick overview of OA policies in Europe, to carry out a comparative study of OA practices within European countries, using data from the Web of Science (WoS) database. This analysis is based on two indicators: the OA share that illustrates the evolution over time, and the normalized OA indicator (NOAI) that allows spatial comparisons, taking into account disciplinary structures of countries. Results show a general trend towards the development of OA over time as expected, but with large disparities between countries, depending on how early they begin taking measures in favor of OA. While it is possible to stress the importance of policy and its influence on open access at country level, this does not appear to be the case at the regional level. There is not much variability between regions, within the same country, in terms of open access indicators.
