You've entered a library. The library is known for its large capacity, yet small size. Inside, you are in a room about the same size as the outside. There is one window on each wall (This is a four-sided building), except the side with the door which leads outside. You cannot see anyone inside or outside of the building.
Examining this room shows you that the outside door is the only door in the building. Inside is a desk with three books, red, green, and blue respectively. Their titles are "FICTION," "NONFICTION," and "AUTHORS" respectively.
You hear footsteps from outside, and you see someone carrying a load of books away from the library. You try shouting, but the person is deaf. You really want to read, so you open the red, fiction book. Inside on every page is a picture of a red book, also titled "FICTION"
What are these books, and where did the man with the books come from?
Hints will be provided daily.
