If you study acoustics you should know that a bookshelf is a perfect natural diffusor. The metal panes on a glass ceiling aren't going to do anything to diffuse the sound.
Have you ever listened to a room with hardwood floors vs. a room with carpeting? I can't stand hardwood floors because they echo so much. Just putting a cheap area rug on the floor will dramatically cut down on echo. Hell being surrounded by glass is about the worst material you could have to try and reduce echos.
I don't believe you work as a recording engineer if you think a shelf of books works as a "diffuser". A soft surface like stack of paper (i.e. books) does not diffuse sound, it absorbs it. A complex, yet hard, surface like the lattice work diffuses sound because it splits the wave up into a million little pieces and sends one in each direction meaning the actual echo heard by the originator of the sound is but a fraction of the sound energy remaining.
Yes a hardwood floor absorbs less than carpet, but that's not my point. My point is that a hardwood floor absorbs much more than a single row of built in book shelfs where none of the paper is exposed except the hard spines of the books. And a wood floor is a FAR better dampener than a stone like the majority of surfaces in both examples.
I actually do know what I'm talking about because I'm a musician and worked as an appraiser of professional AV equipment for a couple years. No one installs carpet in a studio and expects that to make a major difference, everyone installs it because its slightly better than wood or concrete and instead relies on acoustic foam to actually do all the work. I know enough from what I learned doing that to know the difference between diffusing sound and dampening it which you don't apparently understand. No one attempts to diffuse sound in a studio because it will still get into the mics somewhere as background noise, they only dampen sound in a studio. However diffusion can work perfectly fine in other spaces where you don't need dead quiet.
I suggest you read this:
Does the pattern of those diffusers look familiar to you? Yep that's right, appropriately spaced blockages such as the lattice are perfect ways to break up and diffuse echoes.
