You can install the Amazon Library Linky Chrome extension from the Chrome Store.
I ported the Amazon SPL Linky Greasemonkey script to Chrome and made it a proper Chrome Extension. This extension can search any Bibliocommons library, and has an options page where you can select which library you want to search. All of the participating Bibliocommons libraries are supported (about 50).
[Update:] You can see the source code here: Amazon Library Linky on Github.
If you try it out, will you let me know how it works for you?
