Best Book on the N-Body Problem?

[Geremia]

What is the best book on the n-body problem, one that would cover all the different numerical and analytic methods of solving it? I am looking for something similar to this (http://www.amara.com/papers/nbody.html) but more comprehensive, e.g., perhaps with quantum n-body methods, too.

Thanks. This looks like a good quantum one. What about classical ones, too?
