Connecting to library resources from off site:
Use the Princeton University VPN or EZProxy Service to connect to library resources, such as databases, e-journals and e-books, from home or on travel. For information on setting up or using these services, visit Connect from off campus.

EZproxy *new*
The EZproxy service does not require any configuration. It can be utilized directly from our Articles and Databases list. Off-campus users will be routed to the requested resource through the EZproxy service when a resource requires authentication. If the EZproxy services produces an error, use the University VPN as an alternative.
Resources marked "Library Web Computer" do not work through EZproxy, as these Library Resources are available only from designated Library Web Computer workstations physically located within the Library premises.
To report an EZproxy problem, contact lsupport@princeton.edu.

Note: Princeton VPN and Proxy service are services provided by Princeton University and are different from the PPPL VPN. You will need your Princeton NetID and Password to set up the Princeton VPN or use the Proxy Service. The Princeton NetID is the portion of your @princeton.edu email address before the @ sign. For more information about the Princeton NetID visit the Princeton NetID FAQ.

Troubleshooting access to journals and databases:
Short list of possible reasons you may be having difficulty connecting to online journals or e-books at PPPL.

  • In order to ensure the journal/publisher recognizes that you should have access, it is best to use the links provided by the Library. Trying to access a journal from Google may not "authenticate". Use either the Main Catalog, E-Journals , or Plasma Physics E-Journals page to find a link to the journal.
  • Switch browsers. In particular, Science Direct, Scopus, or any of the Elsevier Sciverse Products only support Internet Explorer and Firefox browsers.
  • Try navigating directly to the journal rather than using the Find it at PUL button Sometimes, if the citation in a database does not exactly match information at the journal webpage, the Find it at PUL button will not connect. This has been known to happen in linking from Web of Science to a Science Direct Journal. If the Volume number does not match, Science Direct displays an error message that looks as if we do not have access to the journal. Go to the Main Catalog or E-Journals list and search for the title of the Journal. Follow the links and navigate to the volume, year, and issue of the article you are looking for.

If you continue having difficulty accessing an online journal or database please report the problem to Willow Dressel, wdressel@princeton.edu.
