DESCRIPTION:We present in a unified way the nested Bethe ansatz for spin c
 hains based on gl(n)\, gl(m|n) and their deformations. We perform the ansa
 tz for closed and open spin chains. In the case of open spin chains\, we u
 se diagonal boundary conditions. In all cases\, we deduce a recursion form
 ula\, and a trace formula for Bethe vectors.
