To me the actual book section of Oodi is not particularly interesting/inspiring/impressive. It's not bad, but it is pretty mundane and gets overshadowed by all the other stuff going on in the building.
Famously the actual main library at Pasila has a much larger book collection. Oodi is more of a community space / show piece.
Fair, but it is part of a pretty large library system and you can order whatever you want to pickup at Oodi
