The WZ (Wilf-Zeilberger) method is a very efficient way of finding
proofs of binomial or hypergeometric identities. But there is much
more to it than that. I will talk about two interesting aspects of the
WZ method: a combinatorial interpretation that applies in some cases,
and how the WZ method can be used to unify identities in a way that is
more general than the traditional hypergeometric classification.
