ISBN?

Oh noes! Where have the ISBNs off the Book pages gone? That is a major part of the details of the product and maked it much easier to find your own item in the mass of different versions. I'm going to be moving away from the majority of my collection and I thought that Listal was going to be my link to everything about them so I didn't have to phone my mum to tell me individual ISBNs when looking for the specific copy of a book. :(

I've added it back with isbn 13 as well (which is not on many books yet)
