Open Access and Licensed Resources

The Library connects you to online resources from across the internet, including open access resources that are free to all, and licensed resourced that we have made available to you through agreements between SU and publishers. Licensed resources require you to prove your affiliation with Seattle University before you can access them, which they usually do by checking that the IP address of the computer requesting access to the platform or document.

In order to make sure that all SU researchers, whether they are on campus, at home, at work or anywhere else, appear to our content partners to be coming from an SU controlled IP address, we run your traffic to our licensed collections through a proxy server.

The Proxy Server

Our proxy server, runs EZproxy, the most commonly used library proxy worldwide. EZproxy runs in a server on campus and routes all your traffic to and from a library database through itself, making you (wherever you are) appear to the remote server to be on the SU campus. This allows all of our researchers, where they are working, to enjoy full access to all the content licensed for them by SU.

EZproxy flow

You authenticate yourself to the proxy server (and to the library catalog) using the same credentials you use to access your SU email, and other campus resources. Learn more about your SU Account.

Links proxied through EZproxy have a specific, predictable structure, making it possible for you to see at a glance if you are on a proxied resource, and to copy or create proxied links you can share with other SU researchers.

An alternative to the proxy server

Often businesses and medical agencies have strict firewalls in place to protect their network and users. In these cases, proxy access may not work.

You may be familiar with the campus computer labs, and the wide range of software installed there for your use. Since Fall 2009 these resources have been made available to you from any computer with a broadband internet connection. One advantage for library patrons of this system is the ability to use a virtual lab computer to do your library research, giving you a virtual-on-campus computer from anywhere.

If the proxy does not work for you, try a virtual lab computer. Click the "HTML Access" option to use a virtual lab computer from anywhere, or download and install the client software.

Comcast/Xfinity Home Internet Customers

We have been seeing a small number of reports recently, from Comcast Xfininty home internet customers, of a browser security error when attempting to access our proxied resources. If you are Xfininty customer running into this problem, we have a fix. Unfortunately it involves turning off a security feature.

SSL Error message

Xfinity xFi Advanced Security is a feature that used to cost about $80 per year, but recently Comcast began to offer it for free, so people have been turning it on. If you do turn it on, along with its useful security features, it currently blocks access to the SU Proxy server, which you use whenever you access our online library databases.

Disabling and Re-Enabling Advanced Security

From Comcast/Xfinity Disabling and Re-Enabling Advanced Security

  • You can disable the Advanced Security feature in xFi by navigating to More and selecting My Services. From here, select Disable under xFi Advanced Security and follow the on screen prompts.
  • Once disabled, you will lose 24/7 threat monitoring and real-time reporting on your home network.
  • If you have disabled the Advanced Security feature, you can re-enable it by navigating to More and selecting My Services. From here, select Enable under xFi Advanced Security and follow the on-screen prompts.

If you are unable to use these instructions to solve your Comcast security problems, your best bet is to use a virtual lab computer. Click the "HTML Access" option to use a virtual lab computer from anywhere, or download and install the client software.

We are working with the vendor of the EZproxy software, and with Comcast/Xfinity to find a better solution to this problem in the future.
