Disclaimer in book
Small piece of publishing history: (On page 205 of "The book publishing industry" by Albert Greco)
Houghton Mifflin published Leonard Shatzkin's In Cold Type: Overcoming the Book Crisis, an intelligent critique of the marketing and distribution of books in the United States. This book was so contentious it contained a disclaimer from the publisher, an exceptionally rare event in the world of publishing; even Mein Kampf (also issued by Houghton Mifflin) does not contain a disclaimer from the publisher.
You can see the disclaimer here.
