I used to have more books in my house, but I've donated most of them to public libraries or taken to the library I have in my own classroom. I've created a project with my students named take-a-book-a-day in which they pick the book they want to read at home.
However I still have a few of them, not in a shelve but everywhere. I decor with books and you would see them on side tables, in the kitchen, center tables, wall niches, bedrooms, bathrooms... Books are precious things to display. I stack a few and place a candle on top and makes a great centerpiece.
Here a collage of a few book corners in the house.
