This tool takes you from an Amazon page to the UIUC library catalogue entry for the same book. This is how it works:
In Firefox, open the attached html file, then click and drag the link
it contains to your link toolbar. Find a book in Amazon (like this one: http://tinyurl.com/qevr3), then click on the "UIUC Catalogue Link" icon on your toolbar. A new window will open; toggle to it. (If a new window doesn't open, it means we
don't have the book.)
