We compute the number of perfect matchings of an M× N Aztec rectangle where |N-M| vertices have been removed along a line. A particular case solves a problem posed by Propp. Our enumeration results follow from certain identities for Schur functions, which are established by the combinatorics of nonintersecting lattice paths.
