Abstract
For every biliaison class C-M of Buchsbaum curves of P-3 we prove that the leftmost shift in which there are smooth and connected curves is the same as for irreducible curves. As a consequence, every irreducibl e Buchsbaum curve has a flat deformation with cohomology and Hartshorn e-Rao module constant which is smooth and connected.
