Zeta functions over zeros of general zeta and L-functions

We describe in detail three distinct families of generalized zeta functions built over the nontrivial zeros of a rather general arithmetic zeta or L-function, extending the scope of two earlier works that treated the Riemann zeros only. Explicit properties are also displayed more clearly than before. Several tables of formulae cover the simplest concrete cases: L-functions for real primitive Dirichlet characters, and Dedekind zeta functions.
