 * 2) "Respect for commercial opportunities." -- the use of a book cover to illustrate the article does not diminish the commercial opportuninities of the publisher, on the contrary, it probably helps.
 * 3) "Minimal use." -- This is the only picture for this book cover on the article, and is low-resolution enough that it could not easily be used for other purposes.
 * 4) "Previous publication. Non-free content has been published outside Wikipedia." -- Scans of this cover are widely available on eBay, Amazon, and B&N sites already.
 * 5) "Content. Non-free content meets general Wikipedia content requirements and is encyclopedic." -- This illustrates a notable book, thus is encyclopedic.
 * 6) "Media-specific policy. The material meets Wikipedia's media-specific policy." -- yes, per above.
 * 7) "One-article minimum. Non-free content is used in at least one article." -- This cover is in the infobox for the article Interstellar Pig
 * 8) "Significance. Non-free media is not used unless it contributes significantly to an article." -- This cover, as part of the book, is relevant to a fuller understanding of the novel. It also illustrates a critical part of the story.
 * 9) "Restrictions on location. Non-free content is used only in the article namespace." -- As of July 9 2007, this image is only used on Interstellar Pig.

In summary, this image passes all our non-free use guidelines. It is no bigger than necessary in the article it is in, it could not be replaced by a free image, and it is significant in its article.
