As of January 2016, all NSF-funded research outputs and their supporting data must be available for download, reading, and analysis free of charge no later than 12 months after initial publication.
A data management plan is required on submission of your proposal and specific guidance can be found for each discipline.
NSF policy requires that a copy of published outputs, including peer-reviewed journal articles, juried conference papers, and supporting data be made available through public access NSF-designated repositories hosted by the Department of Energy (DOE).
The NSF intends to permit bulk downloading via DOE PAGES “while protecting the integrity of the scientific record from unauthorized redistribution of scholarly content.” The DOE currently has a download limit and also relies on fair use to allow others to engage in limited downloading.
From 1 March 2015, authors of research papers generated from research either fully or partially funded by the NRF, when submitting and publishing in academic journals, should deposit their final peer-reviewed manuscripts that have been accepted by the journals, in the administering institutional repository (IR), which is OPEN UCT for UCT NRF grantees.
