From 2005, this 116 page monograph describes itself thuswise: "...It is designed to give readers an understanding of the historic balance between copyright and the public domain as it was written into the U. S. Constitution; how copyright and trademark laws have evolved over time; what they are intended to accomplish; and how you can make sure you understand, benefit from, and follow them. This book is not a how-to or a practical compendium, but rather
a clear explanation of a topic that can appear so complex that those who need to know about it often avoid the topic altogether."
