LibX for LSU Law Library: Home

Streamline the research process with this convenient extension for Firefox and Chrome.

What is LibX?

LibX is an open source add-on and extension available for Chrome that extends library resources and services to your browser. Firefox 57 and higher is not compatible with LibX due to a change in the add-on framework. 

Once it is installed, you will see a new icon next to your browser's search bar:

With LibX you can:

  • Search the Law Library catalog, the LSU Libraries catalog, Google Scholar, HeinOnline, LegalTrac and more
  • Re-load pages to authenticate for off-campus access for pages such as journal articles

LibX also expands the functions available through the right click of your mouse so that you can quickly access search options.

By using this extension you may send the URL of pages you are currently visiting to your library's catalog server. Such information is sent only if you are actively using the extension; it is never sent automatically. If you wish to avoid this you must turn off the referrer URL by setting network.http.sendRefererHeader to 0 in your preferences.

If configured for your edition, you may also send URLs to your library's EZProxy authentication server to determine whether the current page can be proxied when using the right-click context menu. Use the LibX -> Preferences panel to turn this services off if desired.

For more information about LibX, visit the LibX Homepage.

Starting with LibX 2.0, Google Analytics is being used to track how users interact with LibX. the following events are tracked:

  • First-time installation of LibX.
  • Browser Start with LibX installed (to obtain an estimate of active users).
  • Use of the autoedition facilty - if a user activates an edition suggested by IP.
  • When a user performs a search (or preview) via a configured catalog. (Just the event is logged, not what the user is searching for).
  • When a user interacts with a LibApp - for instance, when a user clicks on an autolinked ISBNs, we track this event (we do not track the page the user is on, or the ISBN being clicked on). This will help us learn how LibApps are used.

LibX users can turn off (opt-out) Google Analytics in the preferences.
