Open Access is often considered as particularly beneficial to researchers in the Global South. However, research into awareness of and attitudes to Open Access has been largely dominated by voices from the Global North. A survey was conducted of 507 researchers from the developing world and connected to INASP’s AuthorAID project to ascertain experiences and attitudes to Open Access publishing. The survey revealed problems for the researchers in gaining access to research literature in the first place. There was a very positive attitude to Open Access research and Open Access journals, but when selecting a journal in which to publish, Open Access was seen as a much less important criterion than factors relating to international reputation. Overall, a majority of respondents had published in an Open Access journal and most of these had paid an article processing charge. Knowledge and use of self-archiving via repositories varied, and only around 20% had deposited their research in an institutional repository. The study also examined attitudes to copyright, revealing most respondents had heard of Creative Commons licences and were positive about the sharing of research for educational use and dissemination, but there was unease about research being used for commercial purposes. Respondents revealed a surprisingly positive stance towards openly sharing research data, although many revealed that they would need further guidance on how to do so. The survey also revealed that the majority had received emails from so called ‘predatory’ publishers and that a small minority had published in them.
