You can use this in conjuction with the LibraryLookup tool for the Provincial Library Service Catalogue to order books by Inter-Library Loan that aren’t available locally.
Here’s the bookmarklet: ISBNtoILL.
Drag that link onto your browser’s toolbar. Then whenever you’re using Amazon.com, or another book-related website where the ISBN is in the current URL, click the link to load an Inter-Library Loan request form.
This system works by taking the ISBN from the URL (using the mechanism from LibraryLookup), passing the ISBN to Amazon.com using their SOAP API to get the author, title, publisher and date details, and then simply creating a regular HTML web form pre-filled with this information. When the form is submitted, the actual processing of the ILL request is done by the Provincial Library Service’s server.
