Ross Davies has written this fun article for The Green Bag. Here is the abstract:

Over the past 80 years or so, maps have appeared in many (but not all) of the U.S. Supreme Court’s decisions involving gerrymanders. This papers discusses some of those maps, and also addresses a couple of problems with the way those maps are published (or not published) in the U.S. Reports, in the Supreme Court Reporter, and in online databases of Supreme Court opinions.

There is an accompanying puzzle which is, alas, sold out.
