On the occasion when the article cannot be accessed via library holdings, the extension will then look for an Open Access version via Unpaywall and Core.ac.uk.
With Unpaywall, our pop-ups specify the type of Open Access version in plain text. For example, the below Open Access version provided by our extension via Unpaywall is the "Published Version":
The possible versions from Unpaywall are "Submitted Version", "Accepted Version" and "Published Version". This version classification is only available for content sourced via Unpaywall.
Below is an explanation of each version:
Submitted Version is not yet peer-reviewed.
Accepted Version is peer-reviewed, but lacks publisher-specific formatting.
Published Version is the version of record.
How to customise Open Access pop-up text?
The terminology for these versions can be customised on the dashboard under General Pop-up Settings. For example, you could relabel these as ‘Pre-peer Review’ for "Submitted Version", ‘Post-peer Review’ for "Accepted Version", ‘Version of Record’ for "Published Version".
You could also customise your Open Access pop-up text to further support your patrons by letting them know that they can request a specific version of the article through their library. Please see the below example:
When patrons click "Get Article" they' can be directed to your ILL/DDS form. Patrons can then request the specific version of the article through the library if needed.
