Script Summary: A new update to an old script! Adds a shelfari logo on any book's Amazon page, that links to the book on shelfari.com. Works with books, ebooks, and audiobooks. Updated 8-12-2011 to fix bug that made some shelfari links unclickable.
Based on the script by mathias. I've updated it to work again (it had been abandoned/broken since 2007, and the namespace no longer exists), updated the shelfari logo, and made it target only books, ebooks, and audiobooks.
This userscript will add the Shelfari logo to an Amazon book detail page.
Works on Amazon.com, Amazon.co.uk, and Amazon.ca (I can add other countries by request!).
Note: You must be logged in to Shelfari or the image-link won't take you anywhere.
Update: Updated 8-12-2011 to v2.2, which fixes a bug that made some shelfari links unclickable.
