So 978 introduces the ISBN number. Interesting combined with the information that the inside cover often has an ISBN bar code I think that covers things nicely.

The 978 bit started the idea in my head as I noticed that Calibre was quite happy searching for books that weren't what I recognised as an ISBN number but obviously Calibre recognised the 978 prefix.

Thanks John
