Proxy Servers for Electronic Resources

As I recently struggled with Wolters Kluwer to get our CCH Intelliconnect service to work properly through EZProxy, this topic turned out to be rather timely. Many of our libraries already subscribe to a number of databases and other electronic services, and for law libraries our most popular services such as Lexis and Westlaw require individual logins and accounts. Managing those accounts can be time consuming, but for the user they typically ensure uniform access to the resource from on- or off-campus.

For many of our electronic resources, however, we tend to push for IP authentication instead of user accounts. IP authentication means that we set up the service to recognize the IP addresses (the numeric address of a ‘computer’ on the Internet) for our library or university campus. When a user connects to the service from the library, they are magically (in their eyes) identified to be a legitimate subscriber and granted access. But what about our patrons that are not actually in the library at the moment? One of the benefits of these services is supposed to be 24/7 access…

This is where proxy servers can be a key addition to your service! Basically, a proxy server (such as EZProxy from OCLC) acts as an intermediary for the electronic resource. Users connect to the proxy server, that server authenticates the user in some way, then the proxy server actually connects to the resource. The user never connects directly to the resource, so the only IP address the service sees is that of the proxy server.

In some institutions, proxy servers may also be used for on-campus access as well, simplifying the overall setup and allowing tighter control over who can access the services. Proxy servers might be set up on local servers as hosted services, depending on an institution’s size and resources. It's not always simple to configure or troubleshoot problems, as my recent experiences with Wolters Kluwer can illustrate, but the benefits of a proxy server can be many.
