Authors can self-archive their work by uploading a copy of their manuscript to a personal website or depositing a copy in an open repository. Open access repositories are digital platforms that provide free access to scholarly publications, research data, and other academic resources. They allow authors to make their work openly accessible to the public, without the traditional barriers of cost and subscription fees. They can be discipline-specific or multi-disciplinary, and can be managed by academic institutions, scholarly societies, or commercial entities. See, for example, OpenDOAR for a list of open access repositories, searchable by locale, content, and other measures.
