  We discuss the odd-frequency pairing correlations discovered by Zachar,
Kivelson and Emery (ZKE) in a one dimensional Kondo lattice. A lattice model
that realizes the continuum theory of ZKE is introduced and the correlations it
gives rise to are identified as odd-frequency singlet pairing. The excitation
spectrum is found to contain a spin gap, and a much lower energy band of
spinless excitations. We discuss how the power-law correlations realized in the
ZKE model evolve into true long-range order when Kondo chains are weakly
coupled together and tentatively suggest a way in which the higher dimensional
model can be treated using mean-field theory.
