I'm looking for a good resource that builds the theory of the Radon-Nikodym Property. I'm not particularly interested in the measure-theoretic characterisation; I'd like the geometry of Banach Spaces version, involving strongly exposed points of convex sets. If possible, I would also like the proofs to concentrate more a geometric approach over a convex/variational analysis approach, though this is not a deal-breaker. Thanks in advance.
Chapter 5 of Geometric Nonlinear Functional Analysis by Benyamini and Lindenstrauss is the best geometrically-minded resource on RNP that I know.
