The EC FP7 Post-Grant Open Access Pilot is a funding initiative that supports open access publishing fees for researchers from completed FP7 projects, with a budget of 4 million euros available for over 8,000 projects until April 30, 2017. It covers fees for publications in fully open access journals and has specific guidelines regarding eligibility and the number of funded publications. The pilot aims to facilitate dialogue between researchers, libraries, and publishers while assessing the evolving landscape of open access publishing.
