To be Outside The Shelf or OSTS is to be an innovator of words and ideas beyond the bounds of a collection of books on a shelf or the collection of arts including music, fine art, expressions, writing, and other recorded history.
One who is Outside The Shelf is a writer or artists with a new perspective far from the common view of things. This type of writer has a neo-cosmic delivery and a broad cognizance of the world.
