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 and Firefox that extends library resources and services to your browser.

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
  • One-click access to check the library collection for books you find in Amazon and other popular websites

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

LibX looks for library books everywhere

LibX places the library icon  in web pages you visit if your library has resources related to that page. Whenever you see the icon,click on the link to look at what the library has to offer. For instance, book pages at Amazon or Barnes & Noble will contain icons next to the book name that link to the book's entry in library Catalog. 

ISBN links

A book title can have different ISBNs for the paperback, the hardcover, even for different editions. LibX supports OCLC's xISBN service: you can find a book, given an ISBN, even if the library holds this book under a different ISBN.

LibX also links to the library's catalog where ever it reads any ISBN, ISSN, DOI or PubMed ID.

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.

In addition, you may be sending information such as ISBN and ISSN numbers to OCLC, DOIs to CrossRef's server, and PubMed IDs to the PubMed server in order to retrieve metadata information. If configured for your edition, you may also send URLs to your library's EZProxy to determine whether the current page can be proxied when using the right-click context menu. Use the LibX -> Preferences panel to turn these services off if desired.

Starting with LibX 2.0, we are using Google Analytics to track how users interact with LibX. We track the following events:

  • 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. We are working on a web interface that will allow edition maintainers access to the Analytics data for their editions.
