What is the LibX Toolbar?

LibX Toolbar logo

The LibX toolbar is a free browser add-on for Google Chrome to give you easier access to Fogler Library electronic resources―including journals, indexes, and databases―when you are not on campus.

LibX 2.0 is no longer compatible with Firefox, Internet Explorer, or Microsoft Edge browsers. The current version is for use with the Google Chrome browser on Windows, Linux, and Macintosh OS.

Single Sign-on Option

In lieu of using the LibX Toolbar—unavailable for mobile browsers—students, faculty, and staff may wish to utilize the Single Sign-on feature of myUMainePortal to access paid subscription resources. Simply login, and navigate to  Library web resources by clicking on the Fogler Library icon on the myCampus LaunchPad.
