Currently, there is a problem with article-level linking. What this means is that from our OpenURL resolver / Citation Linker page (see example here) the first link labelled “Article” leads to an error message. You need to click on the link labelled “Journal” and then go to the journal issue & article you want. We are working to fix this.
And just a reminder, the lower link labelled “Article” in the box that refers to DOIs is for a specific version of the article which we may or mat not have access to. That is why it says “Try this DOI link for POSSIBLE full-text if no Article or Journal links above”. In the case of Thieme, it generally points to their German site and we do not have access there.
