I assume your two “N best books” examples are intended as bad examples. Since your other links are to good examples and the whole bullet-list block is introduced by offering “heuristics for finding good starting places”, I think it would be worth making it even more explicit that they are intended as examples of what not to do (rather than e.g. a couple of rare counterexamples to the general pattern you’ve just mentioned).
