A mirror doesn't reverse left to right nor up to down.  The fact that inanimate
objects like text appear reversed, is that you turned the book around 
yourself to hold it up to the mirror.  If the book were transparent and
you tried to read it while holding it up to the mirror, you would
be able to see that the letters are reproduced in exactly the way
you see them through the transparent book.

Here is an interesting fact about mirrors: The amount of your body
you can see in a mirror does not vary with your distance from the
mirror, if you stand back you can't see a greater proportion of yourself.
