Lamb question

I am starting this discussion because I do think that this is NOT a leather bound book, rather a flexibound. The difference being that Leather bound means that it is a panel that has been covered by leather (or for our purposes, imitation leather) This is imitation leather, but it's not hard panels covered in it, instead it has all the trappings of flexibound books which have a pliable leather imitation covering. I imagine that the publisher wants it to be listed as a leather bound book, but should it be changed here? I think so.
