Off-Campus Access to E-Resources


General Information


Web-icon

If you would like to connect to electronic resources (e.g. journals, databases, etc.) provided by Columbia University Libraries from off-campus, please use the 'remotely accessible URL' links to these resources that appear on the libraries web site and in CLIO.

These 'remotely accessible URL' links look like:

http://www.columbia.edu/cgi-bin/cul/resolve?#####...

When you access that URL from off-campus, you may be prompted to enter your UNI and password.

If you encounter problems when using our electronic resources, please let us know via the problem report form.

Virtual Private Networks (VPN) Services

Cisco VPN Client software enables you to create a secure connection, a Virtual Private Network, over the Internet, and lets off-campus faculty and staff access administrative applications normally available only on campus.

It is needed to access FFE, AP/CAR and other financial applications on the mainframe from remote locations.

There are currently no plans to extend this service to the rest of the Columbia Community, however, Columbia University will be providing secure WiFi in the near future. An informative article that examines security issues related to both VPN’s and secure WiFi may be found here.

Download and installation of the Cisco VPN Client software is permitted to faculty and staff of Columbia University.

If you have trouble establishing a VPN connection, take a look at these solutions to common problems. Your problem may be something you can solve yourself.

If you are unable to solve the problem yourself, do one of the following:

 

E-Link is a small blue icon that appears in the results list of article databases.

When you click it, it links your search results to a variety of other research options:

  • Checks if the full text of the article is available online for immediate access
  • Searches CLIO, the library catalog, to see if the journal or book is in the library
  • Submits an Interlibrary Loan request

Just click on the e-Link icon to see the menu showing the options available for your article.

Logging Into E-Resources

To authenticate or log in, you need a University Network ID (UNI).

If you already have a UNI, please follow these instructions to log into restricted services:

  • When prompted for User Name, type your UNI.
    Do not type @columbia and do not type uppercase letters.
  • When prompted for Password, type the password associated with your UNI.
    Do not type uppercase letters, unless you created your password with uppercase letters.

If you are not able to log in, and you are currently a Columbia student, faculty or staff member, consult the E-mail & Computing: Computer Support page.

 

Connection Problems from Off Campus

If you are not prompted to log in, and you are trying to access our services from a commercial firm, it is possible that your firm has a "firewall" in place. If so, this could be preventing you from gaining access to our proxy server, which would, in turn, allow you to log into our restricted services. You can investigate this with the technical support staff at your firm.

If you confirm that you are behind a firewall, you need to ask your technical support staff to open the following hosts and ports:

greenleaf.cc.columbia.edu:2048
greenleaf.cc.columbia.edu:2443
arugula.cc.columbia.edu:2048
arugula.cc.columbia.edu:2443

 

When an E-Resource is Unavailable

Occasionally, for a variety of reasons, a resource may be temporarily unavailable. For example, the system load may be unusually heavy. If a resource is unavailable, just try again later.

If a resource is consistently unavailable, please use the E-Resource Problem Report form. You may also report the problem to a reference librarian

If you are not able to log in, and you are currently a Columbia student, faculty or staff member, consult the E-mail & Computing: Computer Support page.

 

Accessing E-Resources
