Against Intellectual Monopoly is a book by Michele Boldrin and David L. Levine that, 
making honor to its title, can be downloaded on its website. The material is really interesting and full of supported examples and claims. Although the sources are well documented, you won’t find all the endnotes in the main text. The authors have placed at the end of each chapter for your convenience.
The main idea of the book is that evidence goes against the notion of intellectual monopoly as a good mechanism to stimulate innovation and “as a practical matter is damaging to growth, prosperity and liberty.” Basically, the authors try to explain that intellectual property can not be considered in the same way that ordinary property.
A must read if you going to redact certain kind of policies.
