 //<pre>
 //This code will change ISBN links to point to the url of your choice,
 //instead of Special:Book_sources. 
 //
 //How to use it:
 //
 //First, you must copy this code to your user javascript page. This is 
 //at User:<your username>/monobook.js . My username is Lunchboxhero so
 //my javascript page is User:Lunchboxhero/monobook.js . You must be logged
 //in to edit your javascript page.
 //
 //Once you have copied the code and saved the page, you need to refresh your
 //browser's cache. For Mozilla/Safari/Konqueror: hold down Shift while clicking 
 //Reload (or press Ctrl-Shift-R), IE: press Ctrl-F5, Opera: press F5.
 //
 //The code should now work, as long as you are logged in.
 //
 //You can change the destination URL. Go to [[Wikipedia:Book sources]] and copy 
 //the URL of the site you want to use (right-click the link, then click "Copy Link 
 //Location", "Copy Target", or similar). Put the new URL between the quotes next 
 //to magicURL, in place of the URL now there.
 //
 //Good luck, and if you have any questions, leave a comment on the discussion
 //page of User:Lunchboxhero/monobook.js . Thanks to Superm401 and drrngravy for their
 //improvements.
 //
 //(Every line that starts with "//" is a comment and can be discarded.)
