Acknowledgements 

I first undertook this project in the summer of 2013 with the hope of helping students avoid the high costs of textbooks, generating content that could be used and improved upon by others, and tailoring my materials to my own needs. In 2021 we undertook a major revision I hope you will enjoy and disseminate it widely. This project is a team one and many people deserve credit.

First, the H20 team for helping to create this product and teach me to use it: Catherine Brabston, Dustin Lewis, Emily Ellis, Matthew McKay‎ and Shailin Thomas. 

Second, my team of RAs/TAs who helped me edit materials, generate new content, etc. In prior editions they included Jerry Cedrone, Shing-Shing Cao, Jenny Du, Jeremy Feigenbaum, Aaron Hill, Laura Myron, Ashwin Phatak, Veronica Sauer, Niko Paladino, Azucena Marquez, Diego Negron-Reichard.

For the 2022 edition, William Locke led and coordinated the team of RAs in editing materials and contributed to improving and updating this casebook. He was in every respect my co-pilot for the project, and I thank him immensely.

For the 2023 edition, Shing-Shing Cao led the effort with the help of Jaime Miguel El Koury.

Finally, I thank my colleagues Bill Rubenstein and Jim Greiner for sharing their materials with me when I first started teaching this course – much of how I teach it is inspired by them.
