OHSU

How the Off-Campus System Works

Adapated with permission from Johns Hopkins University

Introduction

Many of the electronic resources provided through the OHSU Libraries are licensed to be used only by current students, faculty and staff. To comply with these license agreements, access is often restricted to the Internet Protocol (IP) address range associated with the campus network. For students, faculty and staff who access the Internet through third-party Internet service providers (ISPs) this presents a problem. The IP address owned by the ISP will not be recognized as a valid OHSU address and access to the licensed resource will be denied. To remedy this situation, the OHSU Library has installed a program called EZProxy on an OHSU server. OHSU faculty, staff and students with current library privileges may use this program to access IP-authenticated resources from off-campus.

What is EZProxy and how does it work?

The server and EZProxy software acts as an intermediary between users and the Internet. It allows an authorized user to access almost all restricted electronic resources available through the library Web pages from home or on the road. This type of remote access is often referred to as "proxy" access.

Links for off-campus users include a special string of code that invokes the EZProxy software. For example, the URL for Archives of Dermatology is http://archderm.ama-assn.org The off-campus URL for this title is: https://liboff.ohsu.edu/login?url=http://archderm.ama-assn.org/.

When a user clicks this off-campus link, the EZProxy/off-campus system will prompt the remote user to log in with his/her last name and library barcode. If the login is successful, the EZProxy system will act as a proxy to the restricted resource. The EZProxy system will request the page from the Web server and then pass it back to the remote user. The EZProxy system is allowed to access the page because it is on the OHSU network.

What can I access from off-campus?

You may access various databases, electronic journals, and electronic books, all linked from catalog.
