Off-Campus Access

Report an Access Problem  |  Frequently Asked Questions 


Starting from the week of August 10th, 2020, off-campus access to most library licensed e-resources will be through a service called EZproxy. This service works by using links that have a URL prefix prepended to the front of the e-resource, for example:

If you are coming from an IP address for Yale University or Yale New Haven Hospital, you will not be prompted to authenticate. If you are coming from a network location outside of the IP range for Yale University or Yale New Haven Hospital, the prefix will prompt you to authenticate.

Yale University users should authenticate using Yale CAS (with DUO Multifactor Authentication), and YNHH users should use their Epic credentials to authenticate.

EZproxy does not require any installation or setup. All you need is a properly prefixed URL for the e-resource you are trying to access. Links to e-resources on our website are being updated with the prefix. If you have already bookmarked a direct URL to a specific e-resource, you should update your bookmark with the latest link from our website. However, starting your research from the Library website is the easieast way to make sure that you are using the most up-to-date links to online resources.

Yale VPN & DUO Multifactor Authentication

While the Library uses EZproxy as the primary method of off-campus access, the University's VPN service continues continues to be a valid method of remote access. If you are connected to the University's VPN, you are considered on campus and will not be prompted to log into EZproxy.

If you want to use the VPN to access Yale resources. Visit this page, click 'How Do I Get It' and follow the instructions based on your affiliation.

You'll also need to download DUO - Multifactor Authentication. Yale automatically creates your account at DUO Security, Yale's multifactor authentication provider, when your Yale affiliation is established. Once your DUO account has been created, enrollment in the multifactor authentication will be initiated via an email or upon entry into a protected resource.

Medical Library Proxy Server

Note: the Medical Library Proxy Server service will be discontinued once EZproxy rollout is complete.

Request a proxy server account here: Medical Library Proxy Server signup page.

Information about our proxy server here: Medical Library Proxy Server

The Medical Library maintains a proxy server primarily for the use of Yale-New Haven Hospital employees and affiliates who wish to access library online resources from outside the Medical Center. It may also be used by faculty, students and staff of Yale University who, for some reason, are unable to use the preferred remote access option, the Yale VPN.

Access from Clinical Locations

This page provides information on offsite access options at some of the major clinical rotation sites, including Yale-New Haven Medical Center, the West Haven VA, Waterbury Hospital, Bridgeport Hospital and the Connecticut Mental Health Center.
