Abstract: 
We present in a unified way the nested Bethe ansatz for spin chains based on gl(n), gl(m|n) and their deformations. We perform the ansatz for closed and open spin chains. In the case of open spin chains, we use diagonal boundary conditions. In all cases, we deduce a recursion formula, and a trace formula for Bethe vectors.
