Fair use rationale

This image is of book cover(s), and the copyright for it is most likely owned either by the artist who created the cover(s) or the publisher of the book(s). It is believed that the use of low-resolution images of book covers to illustrate an article discussing the book in question on the English-language Wikipedia, hosted on servers in the United States by the non-profit Wikimedia Foundation, qualifies as fair use under the copyright law of the United States. Any other uses of this image, on Wikipedia or elsewhere, might be copyright infringement. See Wikipedia:Non-free content for more information. Fair use //en.wikipedia.org/wiki/File:Mao_unknown_story.jpg true

The cover of the book is copyrighted material and will always be copyrighted. Thus it is fair use to use a low-resolution image of the cover to demonstrate the cover of the book in question on the Mao: The Unknown Story article, as well as that of the author, Jung Chang, because no free version can ever come into the public domain.
