I just found this great little tool to add to my tool bar while browsing the Daily MashUp. Its called LibX and is a beta tool for Firefox from MIT.

1. Toolbar: LibX is a Firefox toolbar that allows you to quickly search the Barton catalog, Vera, Google Scholar, the SFX FullText Finder and other search tools
2. Right-click menu: when you have installed LibX you can highlight text on a web page or PDF and right-click for a menu of search options
3. Embedded links: LibX will also embed links on search results in Amazon, Barnes & Noble, Google Scholar, NYT Book Reviews, and more that will lead you to MIT-only resources

While you’re on this page, be sure to hit the “Library Betas” link at the very top of the page to find other projects that the MIT library has developed or is in the process of developing.
