The migration to the new SpringerLink platform took place last week. Since then, we’ve been unable to access some archival journal content and some eBook content on the new platform.
Springer is aware of the problem and is taking steps to resolve it. In the meantime, you should be able to access archival and eBook content on the old platform, which can be reached by clicking on “access old SpringerLink” in the upper right hand corner of the new platform.
