Q. Green open access requires depositing articles in an open access repository. How do we check if we are able to deposit a version of an article?

You may check the Sherpa-RoMeo website: http://www.sherpa.ac.uk/romeo/ to see if a particular publisher allows self-archival in an open access repository, which version is allowed and if any embargo is imposed. Alternatively, you may check the publisher’s website directly for more details on its self-archiving policies.
