Types of OA Publishing
The term "Open Access" covers a variety of publishing types and agreements. Listed below are definitions, from most to least "open."
- Diamond OA - the full manuscript version is completely open and available, no author fee (APC)
- Gold OA - the final version of the manuscript is made openly available immediately upon publication by the publisher, may or may not entail an APC
- Green OA - a manuscript version, typically the pre- or postprint but not the publishers final copy, is made freely available in a repository such as the UTHSC Digital Commons or PubMed Central. If authors have signed a Copyright Transfer Agreement (CTA), publisher's policy will determine which version of an article can be archived in a repository. Most publishers allow some sort of green open access. Authors can check their CTA for this information.
- Hybrid Journal - a type of journal that allows authors the option to publish their manuscript OA if desired, typically for a much higher APC than full OA journals. Other submission will remain behind a paywall.
- Bronze OA - the manuscript is made openly available only through the journal or publisher website. The author does not pay a publishing charge. However, the publisher retains the copyright and can stop the publications being freely available at any time. True Open Access publications have a specific licence (often a Creative Commons licence) that means the publication is irrevocably Open Access and the terms of use and reuse are clearly stated.
Manuscript Types
- Preprint - a manuscript draft that has not yet been peer-reviewed or formatted by a publisher, often distributed ahead of publication via preprint repositories such as arXiv
- Postprint - a manuscript that has been reviewed and corrected, but not yet undergone formatting and typsetting by the publisher
- Publisher's Version or Version of Record (VOR) - the final, formatted version of a publication that appears online or in the journal
