bookcases flanking things with sconces

I like this concept for a guest room where you can fill it with pretty things but it's out of the way and completely space saving. And that you know they need lamps but there's no space so they sconce.

I consider this combination for the office a lot but I dunno if I need more bookcases in there. Plus I want them to be very specific like how the bottom is deeper than the top shelves. What's is that?

I am on my laptop on a Saturday while Alice watches a movie so I can kind of ignore her while Matt and Wally nap because a last minute job came up and now I guess I gotta work. I need more work. Xo.
