What is a one-sentence summary of the following article?
Books can take up a lot of visual space in the bookshelves. If you stagger other decorative pieces into your bookshelves, this can help break up the space from the monotonous look of the books.   If you have collections with items like bowls, pictures, vases, statues, paintings, or clocks, these can be great things to display on your bookshelves. Arrange some of your books in stacks. Most of us put books into shelves vertically with the spines facing outward. Consider arranging  a few books on a shelf in a stack in which the lay horizontally. Put the largest book on the bottom of the stack and then move upward with smaller books.Turn the spines outward so you can see the title. When you make room for other items in your bookshelves, you can see the background of the shelves more clearly. Consider painting your shelves a bright color to add a bright spot to your room. If you are renting an apartment and are not allowed to paint your walls (or don't want to take the time to do this), then painting your bookcase is a good way to add your distinctive style to your space. If you prize a uniform look on your bookshelves, then consider wrapping your books in a white paper. You can also achieve a uniform look by using decorative pieces all in the same shade of color (or a neutral color like white or black). You can also place storage bins or boxes in a common texture and color -- like wicker or fabric -- on a bookshelf. This will give a very organized, uniform look to your shelves.

Summary:
Relieve the eye. Add a pop of color. Embrace uniformity.
