Gold open access refers to the open online availability of a final published article (the “Version of Record”) after the payment of article publishing charges by the author, funding agency, or other sponsor. Some funding agencies and legislatures require that authors publish Gold open access and under a Creative Commons License, and may make funds available for authors to pay publishing fees in order to comply with such requirements. Note: ACS AuthorChoice is our Gold open access solution. Open access from ACS is provided either immediately or at 12 months, and Creative Commons licenses are available.
Green open access typically refers to an author’s self-deposit of the accepted manuscript version of an article in a repository for open online availability after some embargo period. The accepted manuscript is the version of the article that has been accepted for publication in a journal that includes, but is not limited to, changes resulting from peer review but prior to a publisher’s copy editing and production. Publishers do not charge authors for Green OA. Increasingly, green open access is a mandatory requirement placed on authors by the funding agency or government that supported the research, or by the author’s employing institution. Note: Where authors are subject to a funding agency or institutional Green open access mandate, the terms and conditions of the ACS Journal Publishing Agreement grant to authors the ability to deposit to repositories the accepted manuscript versions of articles they publish with ACS, for open availability at 12 months. In addition, our ACS Articles on Request linking service enables unlimited open availability of the final published article (Version of Record) to readers at 12 months, at no charge to the author or to readers.
