I know that no one reads this blog anymore, but if you happen to be here and haven't tried out Amazon Light yet, go do it right now. Basically, it's an alternate interface to Amazon, but most noteworthy in that it incorporates Jon Udell's Library Lookup functionality right into the search results page. That is to say, look up any book and (once you've selected your library in the Settings) on the book detail page there will be a button check for that item in your library's catalog. Sure, it's exactly the same as the bookmarklet, but I implore you to acknowledge the coolness of incorporating this application into a much broader suite of nifty features (including BlogThis, del.icio.us, Netflix and Gmail functionality). Trust me, just go check it out already.

Update: I see that Mr. Fagan and Mr. Cohen beat me to this one. I may as well point out that my source was the always entertaining kottke.org remaindered links weblog.
