What I noticed was what seemed to me a distinct space opera bias, combined with all the choices being the "obvious" ones. For example, two Asimov books are on there. Both are his two most famous books, and both are quite space opera-y. I would argue that End of Eternity was his best work and deserves a listing before either of those. Unfortunately, not as many people are aware of it. In the case of Necromancer though I have to disagree with you. I think that it has held up incredibly well, the parts that were weak when it was released (totally screwy view of technology) are still the weak parts, but the strong parts (the vivid imagery for one) continue to be quite effective. Then again, I have a strong cyberpunk/modern bias, I'd also recommend a few of Charles Stross's works :)
