We present new off-shell formulations for the massive superspin-3/2
multiplet. In the massless limit, they reduce respectively to the old minimal
(n=-1/3) and non-minimal (n=−1/3,0) linearized formulations for 4D N=1
supergravity. Duality transformations, which relate the models constructed, are
derived.Comment: 18 pages, LaTeX; v2: minor changes, references adde
