Book recommendations needed

[petrea_mitchell]

It's gift card season and there are a couple sorts of books I would like to get with mine, but I don't even know what sorts of terms to start searching on.

1) Something about different legal systems and the philosophies that go with them. How they shape how people think about what the law is even for, and so forth. Would prefer to focus on modern systems, but historical examples are fine if they help illuminate the present. (E.g. I have come across mentions a few times that things work in such and such a way in France or its former colonies because they were shaped by the Napoleonic code.)

2) How the governments of really huge cities/metropoles work.

Blogs or newsletters are okay too. But no podcasts or YouTube series unless they're scripted, please.
