Books - design statement or just way too many?

I know realtors don't want books or magazines when they show a place. I guess they don't read! And figure neither do buyers (which is why I never really warmed to our realtor in Houston who thought a good library was a landing on a stairway!).  And when I watch those "designed to Sell' shows on cable, they are always getting books out of sight. But...

Books can be a design statment --- as is evident by these bookcases:  http://inspirationfeed.com/inspiration/industrial-inspiration/50-unique-and-unconventional-bookcase-designs/

Not necessarily practical, but then I've never seen the point of arranging books by size and color either --- I have books (can you guess) and I want to be able to FIND them! I need a Dewey Decimal suystem for the home. Anyway...
