The link you provide to back up "people have sued reviewers for including too much of the original tet in the review" doesn't say that at all, though. The Nation lost that case because (quoting from that Cornell article you linked),
> [Nation editor Victor Navasky] hastily put together what he believed was "a real hot news story" composed of quotes, paraphrases, and facts drawn exclusively from the manuscript. Mr. Navasky attempted no independent commentary, research or criticism, in part because of the need for speed if he was to "make news" by "publish[ing] in advance of publication of the Ford book." [...] The Nation effectively arrogated to itself the right of first publication, an important marketable subsidiary right.
The Nation lost this case in large part because it was not a review, but instead an attempt to beat Time Magazine's article that was supposed to be an exclusive first serial right. If it had, in fact, just been a review, there wouldn't have been a case here, because it wouldn't have been stealing.
Anyway, I don't think you're going to be convinced you're interpreting this wrongly, and I don't think I'm going to be convinced I'm interpreting it wrongly. But I am going to say, with absolute confidence, that you're simply not going to find many cases of reviewers being sued for reviews -- which Harper & Row vs. Nation is, again, not actually an example of -- and you're going to find even fewer cases of that being successful. Why am I so confident about that? Well, I am not a lawyer, but I am a published author, and I am going to let you in a little secret here: both publishers and authors do, in fact, want their work to be reviewed, and suing reviewers for literally doing what we want is counterproductive. :)
