Kansas State University Libraries’ proxy URL usually looks like this, and tends to be at the front of a URL: https://er.lib.k-state.edu/login?url=
If you need to add the proxy prefix in front of the resource, use Link It. Link It creates accessible links to materials that are only available through K-State Libraries’ article databases or electronic journals accessed on campus.
However, be sure to test all links off-campus.
If you are unsure if a resource has the proxy URL, please Ask a Librarian.
