Campus Activated Subscriber Access (CASA) - Highwire Press

"HighWire and Google co-developed CASA (Campus Activated Subscriber Access) as an authentication enhancement that improves the authentication for off-campus users of Google Scholar.  CASA is free and is automatically enabled for all HighWire-hosted Journals that are indexed in Google Scholar. How does it work? When a user is on-campus, they often connect to a University network. When connected, if they visit Google Scholar, Google automatically creates an affiliation between that user and their institution.  This affiliation allows Google Scholar to record that the user has subscription privileges granted by that institution. With Google CASA, this same seamless authentication follows the user when they take their device to any off-campus location.   Once the affiliation is created, it grants them immediate access to the articles and Journals that their institution subscribes to even when the user is off campus...."
