Acknowledgements

The creation of this text was greatly facilitated and owes a major debt to Wikipedia and its large number of voluntary contributors. I very liberally copied from many Wikipedia pages and then remixed, edited, adapted and added text. With your continued support and help this book can only get better over time. I urge you to email me with your criticisms and suggestions at nsucher@rcc.mass.edu. This book is made available as an open educational resource under Creative Commons Attribution-Share Alike 3.0 Unported United States License for others to do as I did and improve and adapt to specific requirements. I am grateful for the support provided by the Roxbury Community College’s OER initiative “RCC Go Open” and wish to thank the members of the OER Task Force and library director William Hoag for their unwavering commitment to OER.
