CBS Library provides full-text access to huge volumes of research articles but not all. So how do you proceed, if you happen upon a title that is not readily available from the library collections and if you don't have the time to go through an (otherwise quick) interlibrary loan process? Alternative legal options do exist!
Most publishers allow for the uploading to a repository of an ‘accepted version’ (i.e. after peer-review and before publisher’s layout) of research articles. These articles rarely appear on the first page when you do a Google search – but in many cases, they exist and are free and legal to read and download.
Unpaywall and Open Access Button are both tools that search repositories around the world to help you find these ‘hidden’ versions of articles.
How do they work?
Unpaywall offers a browser extension that will tell you immediately if the desired article is available or not. A small lock will appear on the right-hand side of the browser. If it is grey and locked, no accepted version is available, but if it is green and open, you can click the lock to access an available version of the article.
To see an example of a green lock:
- Install the browser extension
- Turn off the VPN connection to the CBS network
- Open this page (article example)
- Click the green lock on the right-hand side of the browser to access the article
Open Access Button works in a similar way but the Button stays on the top of your browser.
All you have to do is click the Button and it will take you to an available version of the article, if such a version exists.

The consortium agreement between Elsevier and Danish research institutions means that CBS researchers can publish their research as Open Access free of charge in a number of Elsevier journals.
The agreement came into force on January 1 2021 and will run until December 31 2024.
To be eligible for zero-cost Open Access publishing, an article needs to meet the following requirements:
What to do?
When your article is accepted for publication, you will receive an e-mail with a link to the “post-acceptance author journey”. To make sure that your article is published as Open Access at no cost, you need to complete the form as follows:

Which journals are included in the agreement?
Except for about 170 titles, the agreement covers most subscription-based journals.
Check to see if a specific journal is included in the agreement
Open Access journals, i.e. journals that are not subscription-based and where all articles are published as Open Access, are not part of the agreement. If you publish in one of these journals, you will need to pay an Article Processing Charge (APC).
