Let C be an arithmetically Buchsbaum curve in P n and let I C be its ideal. We study C and I C by concentrating on hyperplane sections, especially for n= 3. For example, we consider the problem of lifting elements of I C∩ H (where H is a hyperplane) to I C, and from this we draw some conclusions about the liaison class of C. We also attempt to give good bounds for the degree of a minimal generator of I C, and we strengthen these bounds in case C is integral. We also consider curves which are extremal with respect to our general bounds.
