Different Interpretations - End of Week One Holidays - 14th April

During my research for my essay I found myself getting quite frustrated with trying to come up with a definition for Artist's Books that would cover all the necessary points. It sparked a conversation with my mum as I tried to explain to her what an Artist's Book is (thinking that actually voicing my opinion to someone else may help me realise that I could describe one). I told her that finding the right definition for this has been as hard as finding a correct way of defining Art or What a Book is.

She said to me that questions like that, that are so subjective will never be easy to answer due to everyone's differing interpretations. She then gave me a great example of this. She said:
"You could fill a classroom with people and give them coloured pencils and paper, you could then give them instructions of what to draw on that paper eg. draw a square in the top corner, draw a triangle overlapping the square etc. You can almost guarantee that no drawing will be the same." 

Don't all of these pictures have a square in the top corner with a triangle overlapping? But they aren't all the same. Even though the full room could be given the same set of instructions, everyone interpretates them differently. Much in the same way that people have different opinions of what a book is, or what art is, or what an artist's book is. I think that even if there was a precise definition for what any of these are, people would still find holes and see things differently all based on how they interperate it.
