Welcome to the Princeton University QED website!

QED is a web-based Content Creation and Management System based on MediaWiki software.
This means that once you have logged in, you can start making contributions, such as editing existing pages, creating new ones, and uploading files. However, if you have not done so before, please read the introduction first. Please also note that most but not all pages and uploaded media files are publicly viewable.

The QED website is an academic service run by Princeton University's OIT.

Featured extension: Google Maps can easily be created and displayed on QED.

  • Instructors can establish a Wiki link from Blackboard to QED.

Why “QED”?

The name QED was selected in part to convey the idea that many things can be quite easily done using the QED service, such as embedding a video on a page, managing a large collection of images, or creating a Google map. For example, if you wanted to add a thumbnail with a flyover enlargement as shown below, you would just add the text:

<flyover src="Minard carte figurative.jpg" max=500>=</flyover>

Minard carte figurative

The QED service currently includes a wide range of extensions. Adding and even developing similar extensions can also often be quite easily done, though for security reasons installation of such extensions requires support of a QED systems administrator.

If you would like to edit an existing page or to create a new one, you must first login.

Many hyperlinks have helpful tips (sometimes called tool tips, hovertext, or balloon help) associated with them. For example, to see the hovertext associated with any of the menu items in the navigation box to the left, position the mouse cursor over one of the items, and leave it there for a moment until the hovertext appears.

For other tips, please see QED:Tips.


Current limitations include:

  • There is no support for interactive educational assessment within QED.
  • The contents of uploaded files are not searched when one uses the Search button, but they can in general be searched using Google. To restrict a Google search to this website, use the Advanced search link in the search box.
