In response to this tag I'm gonna cheat... Instead of listing 5 "non-books", I'm going to share 5 pictures of one of a non-book that I never tire of reading on almost a daily basis.
The heavens declare the glory of God;
the skies proclaim the work of his hands.
Day after day they pour forth speech;
Night after night they display knowledge.
There is no speech or language where their voice is not heard.
Their voice goes out into all the earth,
their words to the ends of the world.
