              We give biorthogonal system characterizations of Banach spaces that fail the Dunford–Pettis property, contain an isomorphic copy of $c_0$, or fail the hereditary Dunford–Pettis property. We combine this with previous results to show that each infinite-dimensional Banach space has one of three types of biorthogonal systems.
