'Gold Open Access' Articles in gold open access journals are available to their readers free-of-charge from the moment of publication, without embargo or restriction. Authors may or may not pay an article processing charge (APC) to have their articles published in these journals.
‘Green Open Access’ Also known as self-archiving, is where the author uploads a copy of their article to a freely accessible institutional repository. The policy of each journal is different, some allow authors to archive either pre-print or post-print versions of their articles and some may restrict access with an embargo period. (Source: SHERPA)
