The finite section method for infinite Vandermonde matrices is the focus of this paper. In particular, it is shown that for a large class of infinite Vandermonde matrices the finite section method converges in l1l1 sense if the right hand side of the equation is in a suitably weighted l1(?)l1(?) space. Some explicit results are obtained for a wide class of examples.
