There are three current approaches to Open Access publishing, known as 'Green', ‘Gold' and Gold Hybrid' models.
Green model: Green OA allows authors to self-archive a version of their article for free public use.This is the model supported by the University's Research Repository and other institutional and/or subject repositories where accepted authors’ manuscripts or other pre-publication versions (pre-prints, post-prints, or the ‘Authors’ version) are uploaded at no cost to the author or reader.
Gold model: Under this model an 'Article Processing Charge' is paid by the author, the author’s institution or research funder so that the resulting paper can be made freely and openly available without the requirement for the reader to pay for access, and without the restriction of an embargo period. Gold Open Access journals make every paper freely accessible and the published papers can also generally be deposited in institutional repositories. Biomed Central journals exemplify this model.
Hybrid: In this model only some of a journal's content is openly accessible.These are journals where some authors have paid to make their papers open access but other papers are published under a traditional subscription model where payment is made by subscribers. For example, under Springer's Open Choice and the Taylor & Francis Open Select options, authors can pay to have their article made freely accessible online via the publisher's website as well as being included in the print and online versions of the journal that is available to subscribers. Policies vary from publisher to publisher. Please note that this model is not supported by the University's APC fund (see this page for further details).
Publishers have different policies on the versions of papers they will allow you to self-archive and make openly accessible.. If the work is being, or has been, published by a traditional publisher you may have transferred your copyright as part of the publication agreement.
Often the Submitted Version or Accepted Version of a publication (see below) is permitted to be open and uploaded into an institutional repository.
It is important to understand these terms as they often define the rights/permissions you have as an author.
Authors usually assign their copyright to publishers when they negotiate contracts. The SHERPA/RoMEO database provides a guide to publisher’s copyright policies and the deposit of journal articles on the web and in OA repositories.
See the Author Rights page for further information.
A guide to understanding the core components of OA
The guide provides an easily understandable, comprehensive, and quantifiable resource to help authors make informed decisions on where to publish based on publisher policies.
Copyright is an important component of Open Access. OA journals allow authors to retain copyright, with or without a fee depending on the OA model. Copyright of a scholarly work published in a subscription only journal is signed over to the publisher by the author in the publishing contract.
If authors are familiar with their publishing contracts they will know the potential 'openness' of their work. See the Author Rights page to further understand the author's position and the available copyright and publishing options.
Most publishers will allow some form of a published article to be made openly accessible. Depending on the publisher's policy they will often allow the Submitted version (or pre-print) or Accepted version (or post-print) of a publication to be uploaded into an institutional repository. The definitions of these terms are found above.
