OSF | Green OA Day Wiki

"Green OA Day is a grassroots library initiative to promote and educate about green open access (OA). Green OA Day 2025 will be held on Monday, March 17.

Also referred to as self-archiving, green OA is when authors make a version of their published, pay-to-access works freely accessible on some kind of website or repository so that anyone with internet access can read and learn from it.

Green OA is a cost-effective and equitable pathway to making research open access, especially for authors who can’t afford to pay the article processing fees charged by Gold OA journals. It’s also a pathway towards meeting funder requirements for open access!"
