You're confusing US and UK Law. US case law tends to favour the view that scanned documents become public domain, there is no such case law in the UK. In particular the BL position is that due to the proprietary scanning technology they use they inherit copyright on the new works. You could potentially challenge that position in court, but at the moment there's no evidence for how a court will treat it.
