Green Open Access is the model where the accepted manuscript of a work is made available, usually via an institutional repository, either immediately on publication or after an embargo period. Green Open Access is also known as self-archiving, and is based on the traditional subscription model of publication.
The University of California's repository eScholarship provides a platform to upload the final manuscript of an article in order to comply with UC Open Access policies and/or funder requirements. Authors can deposit their papers through the UC Publication Management System (for senate faculty) or directly to eScholarship (for non Senate authors)
The National Institutes of Health (NIH) require published research that the NIH have funded to be deposited in their repository PubMed Central.
Publishers have policies in place which they define when and to what extend authors can make their manuscripts available under Green Open Access.
