The document discusses the two main routes for submitting papers for open access publication: the gold (paid) route and the green (non-paid self-archiving) route. For the gold route, authors may need to pay an Article Processing Charge (APC) to make the paper openly accessible. APC costs vary by publisher and journal. For the green route, authors archive the paper themselves after an embargo period in an institutional or subject repository to make it openly accessible. Proper notification of intent and process is needed for libraries and departments for both routes.
