The Reading Clerk of the United States House of Representatives reads bills, motions, and other papers before the House and keeps track of changes to legislation made on the floor. During the vote for Speaker at the beginning of each Congress, or when the electronic voting system fails, the clerk calls the roll of members for a recorded vote. Reading clerks work for the Office of Legislative Operations, one of nine offices that fall under the jurisdiction of the Clerk of the U.S. House of Representatives.
