Throughout the Chicago Code, very specific legal definitions are
provided for terminology both specialized and mundane. If you don’t know which
words have special definitions, and what those definitions are, then you can’t
understand what a law really means. Chicago Decoded solves this
problem neatly, by identifying every definition in the Chicago Code and
providing a pop-up definition every time that a defined word appears.
Chicago Decoded isn’t just a pretty website—you can take the laws with
you, too. On our downloads page you can get copies
of all of the laws of Chicago in any format that you like, to do
whatever you like with. They’re available in formats meant for you to read
and in formats meant for software to read, too. If you’re a software developer,
you’ll love our API!
