No. Shibboleth only works for resources that use Shibboleth authentication and are members of the InCommon federation (US Higher Education Federation). Resources not members of InCommon (e.g., European publishers like Springer) can't be accessed through Shibboleth but can be accessed using the proxy server.
Databases accessible through Shibboleth include popular library resources:
EBSCO databases (e.g., EconLit, PsycInfo)
Gale databases (e.g., Expanded Academic Index)
ProQuest databases (e.g. Historical Newspapers)
The list of Shibboleth-enabled databases is growing daily. Check the library's A-Z Databases list for the most up to date list. Shibboleth-enabled resources are marked with .
