Ever find yourself looking at details of a book on amazon.com and wanting to jump to the same book on amazon.co.uk? Or vice versa (often useful if you're looking for more customer reviews)?
Well, I do, and the other day I coded up a bookmarklet to do just that.
To install it, just drag the link below onto the "personal bookmarks/favorites toolbar" in your browser. Then when you're viewing book details on amazon.co.uk or amazon.com, click the button to swap to the equivalent page on the other site.
Feel free to steal/improve the code. If you send improvements to me I may incorporate them into this page.
