The Max Planck virtual Library has been scheduled for termination a considerable while ago.
After a long period of continued availability, vLib services have eventually been downsized.
Most search targets have been deactivated. User login has been disabled. Please click here for more information.
Note that most MPG Library Catalogs continue to be cross-searchable.
Successor to vLib is MPG.ReNa for browsing electronic resources, and its Find Literature service for global searching.
We apologize for any inconvenience,
The vLib project team
