As of March 3rd, 2021, if you are on the VPN and following Library electronic resources links, you’ll be asked to sign in through the proxy server for the first resource you visit if you’re not already signed into the campus single-sign on system. This change addresses many issues people are having with accessing resources while using both the VPN and Library systems. If you run into issues that you think might be due to a combination of the VPN and proxy, please send an email to detailing what resource you’re trying to access and the behavior you’re seeing. 

More information can be found at Accessing databases on and off-campus.
