Instead of paying a fee for downloading the full text take the reference to a freely accessible version!
There is now support for your access to closed journal articles. On our reading room PCs you will find the browser plugin unpaywall, which is available for the Internet browsers Firefox and Chrome.
When surfing on the websites of scientific journals, provider platforms or databases, a green lock signals the presence of an Open Access publication of the article after a few seconds. A click on the symbol “Green lock” leads you to the free full text.
Test the example in the reading room!
We also recommend that you download the plugin for your own use, as unpaywall unlike other sites only identifies legal Open Access versions of paid content. It is also important to note that this open access version does not visually correspond to the publisher’s version, as layout and logos are usually not allowed to be used. Also, an embargo period must often be observed when publishing the preprint or an accepted manuscript. The older the article, the more likely it is to be found.
