The Overdrive.ini file contains settings related to integration with the third-party Overdrive service.

In VuFind 2.0 and later, it may be found in the “config/vufind” subdirectory of your local settings directory. If it does not already exist in that directory, a default configuration can be copied from $VUFIND_HOME/config/vufind and customized. (This keeps your local customizations separated from the default VuFind settings).

You can view the latest version of the file here.
