Budapest Open Access Initiative
The Budapest Open Access Initiative (BOAI) is a public statement of principles relating to open access to the research literature, which was released to the public on February 14, 2002. It arose from a convening in Budapest organized by the Open Society Institute on December 1–2, 2001 to promote open access, which at that time was also known as Free Online Scholarship.
