We review recent results on the role of electron-electron (e-e) interactions - "correlation effects" - in quasi-one-dimensional conductors. Within the Peierls-Hubbard model, we examine the consequences of short range (on-site U and nearest neighbor V) e-e interactions for ground state properties, nonlinear excitations, and optical absorption. Our techniques include quantum Monte Carlo and weak and strong coupling perturbative arguments.
