The authors would like to thank Wiley's acquisitions editor Kyle Looper and project editor Kelly Ewing for guiding them through the creation of a For Dummies book. The authors would also like to thank all the great people of XBRL International and others who they have met over the past ten years as they endeavored to turn the idea of XBRL into a reality for the benefit of everyone around the globe. There are far too many names to mention — you know who you are!

Charlie would like to thank his coauthor and contributors; the book couldn't have been created without them. Charlie would also like to thank his company, UBmatrix, a leading provider of XBRL software, for its support in allowing him the time to create this book and to share what he has learned about XBRL over the past ten years while working with UBmatrix and participating in the XBRL International consortium. Last but certainly not least, Charlie would like to thank his ballroom dance teacher, Carina, who helped him periodically escape from the world of XBRL and hard work involved in writing this book into the world of Foxtrot, Cha Cha, Tango, and Rumba, which helped keep stress levels in check and to otherwise maintain a good state of mind during this sometimes arduous process. (And besides, now Charlie can Tango!)

Liv would like to thank Charlie for sharing his vision of what XBRL could be and the insights gained during the ten years he spent helping to create XBRL in this book. But most importantly, Liv would like to thank the Watson twins, Ellen and Tess, for standing by their mom while she travelled around the world planting the XBRL seeds that ultimately sprouted and helped get us to where we are today. I am so proud to be your mom.
