Positive or negative, it seems odd to include such a large number of reviews at all. I have not seen anything comparable in other wiki entries for books, and you certainly wouldn't see such a thing in a more traditional, printed encyclopedia. Imagine an article on A Tale of Two Cities in the Encyclopedia Britannica that included reviews. Ridiculous. This is meant to be an encyclopedia, not a dust jacket. I'd suggest the removal of the reviews. At most, there should be links to reviews so the excerpts could be seen in context.
