Numbers are annual averages of projections for the next five years. Our overall method of projecting Open Access is detailed in this bioRxiv preprint.
Percent of Usage that is OA
The percent of Usage that is available as Green, Hybrid, or Bronze Open Access.
Percent of Usage that is Green OA
The percent of Usage that is available as Green OA. This is Open Access hosted on open repositories, like Harvard's institutional repository, arXiv, or PMC. Green OA that hasn't been peer-reviewed (preprints, submitted drafts, etc) can be excluded in Settings.
Percent of Usage that is Hybrid OA
The percent of Usage that is available as Hybrid OA. This is Open Access hosted on the publisher site with an open license in an otherwise subscription journal. Usually an APC was paid by the authors when they published this paper.
Percent of Usage that is Bronze OA
The percent of Usage that is available as Bronze OA. This is Open Access hosted on the publisher site in an otherwise subscription journal, but unlike Hybrid it does not have an open license. It is sometimes promotional material, and sometimes open after an embargo in a Delayed OA journal (like Elsevier's Open Archive content). Bronze OA can be excluded in Settings.
Percent of Usage that is Peer-reviewed OA
Percent of Usage that is the peer-reviewed version. This includes all of Hybrid and Bronze, and the portion of Green OA that is an Accepted or Published version of the paper. Green OA that hasn't been peer-reviewed (preprints, submitted drafts, etc) can be excluded in Settings.
