About LibX

LibX University of Minnesota - Twin Cities Edition is a Firefox extension that provides direct access to your library's resources. It features:

Context Menu

Toolbar & right-click context menu: Search your library catalog directly from the LibX toolbar or using the right-click context menu.

Support for off-campus access via EZProxy/WAM: Using the Library's off-campus proxy, you may reload a page through the proxy, or follow a link via the proxy, making it appear as though you are coming from an on-campus computer.

Quick full text access to journal articles: LibX uses Google Scholar to search for articles and directs the user to the electronic copy subscribed to by your Library. Select a citation, then drag-and-drop it onto the Scholar button on the toolbar. You can use this feature even from inside a PDF file, which makes retrieving papers referenced in a PDF file a snap.
To use this feature, your library must be a Google Scholar library, or you must activate this link in the Firefox profile in which LibX is installed: Activate Google Scholar support. (See also LibX FAQ Question 11)

Support for embedded cues: LibX places cues in web pages you visit if your library has resources related to that page. Whenever you see the cue, click on the link to look at what the Library has to offer. For instance, book pages at Amazon or Barnes & Noble will contain cues that link to the book's entry in MNCAT. Cues are displayed at Google, Yahoo! Search, the NY Times Book Review, and other pages. Watch this screencast for examples of this cool feature. (requires Macromedia Flash Plugin)

Support for xISBN: 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.
