No project like this stands on its own. We are proud to be standing on the shoulders of giants who produced great software before us. We would like to acknowledge the following.
We would especially like to acknowledge Jim Leisy of Franklin Beedle Publishers. Jim supported our first book project: Problem Sovling with Algorithms and Data Structures using Python. Jim has generously allowed us to develop the online version of this book and make it avaialable for free. Although you can access the interactive version of this book on line for free, you can still purchase a paper copy of the book from the link provided.
