There are many types of Open Access. Green Open Access for example means depositing or ‘self-archiving’ a copyright-free version of your work in a digital repository, usually in conjunction with publishing in a journal and with an embargo period. Gold Open Access means that the published work is available for anyone to access immediately upon publication. This is also known as gratis Open Access, meaning ‘without charge.’ However, journals and publishers often recoup the costs of making the work available for free by charging an Article Processing Charge (APC) to the submitting author. Libre Open Access is a lot like gratis Open Access with one exception – the content of the article is also free to reuse, remix, and republish.
