//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.
//
//The current magicURL includes Wikipedia's Amazon Referral reference. That means if you click on 
//the ISBN link, go to Amazon and end up buying the book, Wikipedia will earn some small amount
//of money from that sale.  If you don't want to support Wikipedia in this way, but do want ISBNs
//to link to Amazon, replace the current magicURL with "http://www.amazon.com/exec/obidos/ASIN/MAGICNUMBER"
//
//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.)
