The names of members of the House of Representatives elected statewide on the general ticket or otherwise at-large, are preceded by an "A/L," and the names of those elected from districts, whether plural or single member, are preceded by their district numbers.
Many of the congressional district numbers are linked to articles describing the district itself. Since the boundaries of the districts have changed often and substantially, the linked article may only describe the district as it exists today, and not as it was at the time of this Congress.
