Do any CALI Lessons require supplemental materials?

CALI Lessons are generally designed so that students can run them without supplemental materials. However, several Civil Procedure exercises encourage users to read parts of the Roger C. Park and Douglas D. McFarland book called Computer-Aided Exercises on Civil Procedure (7th ed. 2014) (eLangdell Press). This book is available for free in several formats from CALI's eLangdell Press.
