Types of open access
In 2002, the Budapest Open Access Initiative (BOAI) recognized the need for providing open access to research by embracing two modes of publishing, namely: self-archiving of peer-reviewed articles or publishing in an open access (OA) journal. Publishing in open access journals is commonly referred to as Gold OA in contrast to Green OA which embraces self-archiving of final peer-reviewed manuscripts in an institutional or disciplinary repository.
