This book serves as a collection of Open Middle-themed problems. Several of the problems here are exact digital analogues of those found on Open Middle's site, https://www.openmiddle.com/. For these problems, credit and inspiration is attributed to the problem creator(s). Other problems here are characteristic of the Open Middle theme. This volume will continue to grow over time.
