Google CASA versus link resolvers

 Google CASA (Campus Activated Subscriber Access) allows off-campus users to access publisher content as if they were on campus, effectively replacing the need for traditional library link resolvers in several ways:

1. Seamless Access: Users can access content directly through publisher links without additional authentication steps.
2. Persistent Links: CASA links remain valid, providing continuous access to subscribed content even off-campus.
3. Improved User Experience: Reduces the need for complex link resolver systems, simplifying access to library resources.

This improves accessibility and user experience while maintaining secure access to library subscriptions.

Google CASA (Campus Activated Subscriber Access) is a feature that enables off-campus users to access publisher links through Google Scholar. This feature can replace traditional library link resolvers in several ways:

1. Off-Campus Access: CASA allows users to access subscribed articles from publishers without needing to use a VPN or other authentication services. This makes it easier for users to access content from anywhere, not just on campus.
2. Integration with Google Scholar: CASA integrates seamlessly with Google Scholar, which is a widely used academic search engine. This integration ensures that users can access subscribed articles directly from Google Scholar without needing to navigate to the publisher's website.
3. Universal CASA: This feature extends CASA to other websites that support Universal CASA. Users can access subscribed articles from these websites by clicking on the PDF or HTML links, which are marked with a gray badge.
4. Cookie-Based Authentication: CASA uses a cookie-based authentication system. When a user logs in to Google Scholar on campus, a CASA cookie is stored in their browser. This cookie allows them to access subscribed articles off-campus without needing to log in again.
5. Long-Term Access: CASA cookies are valid for a longer period, typically 120 days, which means users can access subscribed articles without needing to authenticate every 30 days.
6. No Need for Library Links: CASA eliminates the need for library link resolvers, which are often complex and difficult to manage. CASA simplifies the process by integrating directly with Google Scholar and publisher links.
7. Enhanced User Experience: CASA provides a seamless user experience by allowing users to access subscribed articles directly from Google Scholar. This eliminates the need for users to navigate through multiple websites or use VPNs.

In summary, Google CASA offers a convenient and integrated solution for accessing subscribed articles from publishers, making it a viable alternative to traditional library link resolvers.
