Open Access: Green OA

What is Green OA?

The basics:
Depositing an article or other publication in a digital repository which is open and searchable 
– Directly (self-archiving) or via a local intermediary
The article/book may have been published via a traditional route
– Hence, the publisher may set an embargo on open access through the repository
– The version made open may be the author's accepted manuscript, rather than the published version
The repository may be:
– Institutional, subject, national, international
– Deposit can be in one or more, as required or found to be useful
In order to meet REF2021 criteria, any journal article which has not been published with Gold open access must be deposited in an institutional or subject repository within 3 months of acceptance. The manuscript must be released from any publisher embargo within 12 months of publication (for REF Panels A & B) or 24 months (REF Panels C & D).

Green @ Hull

To make your research output open via the Green route at the University of Hull, use the Worktribe Outputs module to add a record for your publication, and attach your accepted manuscript. Library staff will validate your record and ensure that your publisher's terms are respected regarding any embargo period or licence restrictions.
The record of your output and the associated manuscript will become discoverable via the University's Repository, and can be utilized in your personal profile on your Faculty website.
Worktribe can hold many different types of research output, including supplementary material and datasets. If you would like any advice on how to deposit your output, please contact
