Funny, I would have thought if anyone valued a quiet space to read without being bothered, it'd be the Finns. Looking at the pics on Wikipedia[0] though, it does look like there are some quieter spaces one can duck into. From what's pictured in the wiki article, it does look more like a tech company office crossed with a community center than a public library to me.
