Publishing Open Access is not necessarily upon payment. Authors may post their works Open Access following different paths:
Green OA - the green road to Open Access provides for the self-archiving of the allowed version of the work in an institutional or disciplinary repository at no additional costs.
Gold OA - implies the payment of an APC – Article Processing Charge to publish either in OA native journals or in those proposing OA options (Hybrid Journals).
Embargo – it is a temporal delay starting from the publication of the article's online first. The embargo is not always mandatory. In such a case, it applies to the allowed version(s) of the work only.
Authors may refer to the Sherpa-Romeo website or contact the Library staff for further information about the version(s) allowed for self-archiving by each publisher.
Publishers usually allow the deposit of the: preprint, postprint, Version of Record (upon payment of an APC or in the cases of OA publishers with no additional costs).

AAAS Open Access
- Green OA
- Embargo – AAAS does not foresee any embargo on the preprint and the postprint on "Science" journals, if deposited in an institutional archive. The postprint undergoes a 6 months embargo if deposited in a funder's archive. Science Advances is an exception, since it is a OA native journal. AAS partner journals do not allow self-archiving for both preprint and postprint.

AAAS news: an addendum to the Author License to Publish concerns copyright retain strategy adopted by Plan S. On a trial basis, AAAS allows authors financed by cOAlition S to apply a CC BY or a CC BY-ND license on their postprint. Starting from January 1st, 2021, this policy is applied on all publications of the Science family and financed by the cOAlition S organizations adhering to Plan S (cf. this link).
