Info on and link to download/install the LibX Claremont Firefox/Chrome Extension, a great shortcut tool for your searches.

What is LibX?

LibX is a Firefox/Chrome extension that allows you to quickly search the Library catalog and other resources directly from your browser

  • Right-click context menu: when you have installed LibX you can highlight text on a web page or PDF and right-click to directly search the Library Search, Google Scholar, or the E-Journals List
  • Toolbar Search:  Library Search, Google Scholar, the E-Journals List


LibX and Firefox 57

If you have upgraded to Firefox 57, LibX will no longer work due to a major change in their add-on framework

We will post here when the developers of LibX have an upgrade available - for now, we recommend you use the LibX extension in Chrome browser.

Install LibX Claremont

LibX 2.0 lets you switch between multiple LibX editions, so if you have access to another LibX library you can easily switch from ours to theirs.

Google Scholar Magic

Highlight text then drag and drop the selected text into the  icon in your toolbar, which will immediately run a Scholar search.

More About the Right Click Context Menu

Highlight text on a web page or PDF document and right-click (or control-click for Mac users) to get the context menu:

From this menu you can:

  • directly search our catalog or Google Scholar (try this with a citation you need!)

Alternatively, instead of right-clicking, you can drag and drop the selected text into the  icon in your toolbar, which will immediately run a Google Scholar search.

Use the preferences link to change which search options show up in the context menu:

More About the Toolbar Search

Click the  icon on the upper right of your browser to open the LibX search box.

The Library Search is the default, but you can click on the arrow next to the database name to switch to Google Scholar or the E-Journals List.

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.
