I have a loft upstairs I use to highlight some black and white Ansel Adams photos, as well as a little library. I needed additional shelving. They look a bit industrial, but look fine with the black and white photos and dark frames I have on the wall. Sturdy and could be used to highlight other items in lieu of books.  They hold a fair amount of books; though on the lower two, you probably should have large books at the bottom ends to hold the other smaller books on to the shelves.
