Tolu Odumosu, a science technology and society researcher at the University of Virginia, says access is a sore point among researchers in the region. While preprints can partly address the problem, other barriers also need attention, such as the prohibitive subscription rates of established journals and fees for publication. Institutions also need to invest more time, materials and space to research, says Odumosu. He would be interested in contributing his work to AfricArxiv if he knew that it would reach an active community of scientists in Africa, he says.
