Benefits of open access (OA) to researchers from lower-income countries: Tracing evidence through an analysis of reference patterns

Abstract:  Making scientific literature freely available to everyone is a main objective of the open access (OA) movement. This may be of particular importance to researchers in lower-income countries, where access to literature is often hindered by high subscription costs. This study addresses this issue by analyzing reference lists of the world’s output of scientific publications over time. The core issues addressed include whether researchers from lower-income countries refer to fewer previous publications when they publish and how this pattern develops over time. Moreover, whether researchers from lower-income countries rely more on literature that is openly available through different OA routes than other researchers is explored. The study shows that the proportion of OA references increases over time for all publications and country groups. However, the main finding is that publications from lower-income countries have a higher growth rate of OA references. This suggests that an increase in OA publishing has been particularly beneficial to researchers in lower-income countries.
