About

Authorized access to licensed electronic resources is based on Max Planck Institute campus IP addresses.

Consequently, when on-campus, users can access content without additional authentication and do not need any user name & password, not even for single sign on.

Please note that not all IP ranges of a Max Planck Institute are authorized but only those used by scientific staff and guests of the institute. View IP ranges publishers & information providers are aware of in SESAM-IRMA.

The Max Planck Digital Library takes care that IP updates are authorized by providers of content licensed MPG-wide.
