other Senate floor staff who report to the secretary are the parliamentarian, bill clerk, and legislative clerk. Administrative functions The first secretary purchased the quill pens, ink, and parchment needed by eighteenth-century senators. Modern secretaries of the Senate have responsibility for the Senate Stationery Room, a multimillion-dollar retail operation that keeps senators' offices supplied. From the beginning, the secretary served as the Senate's disbursing officer, paying senators their original salary of six dollars a day plus travel expenses. As the Senate grew, a separate financial clerk was appointed under the secretary's jurisdiction. In recognition of the immediate and historical significance of Senate bills, resolutions, hearings, and reports, the secretary oversees the Office of Printing and Document Services, the Office of Senate Security (which maintains classified documents), the United States Senate Library, the Office of Senate Curator, and the Senate Historical Office. The secretary also maintains the Office of Interparliamentary Services to provide support for those interparliamentary conferences in which the Senate participates and to assist senators in international travel. Also under the secretary's direction, the Office of Public Records collects and makes publicly available documents relating to campaign finance, financial ethics, foreign travel, and lobbying. In 1789 the secretary was authorized to hire "one principal clerk." This principal clerk, or chief clerk, for many years served primarily as a reading clerk on the Senate floor. But during the 1960s, in response to the secretary's growing administrative duties, the position evolved into that of assistant secretary of the Senate, who oversees the administration of the Secretary's Office, including computers and the secretary's web site. The assistant secretary also performs the functions of the secretary in his or her absence. During the 1960s, under the leadership of Francis R. Valeo, staff positions under the secretary of the Senate were redefined from patronage to professional status, a trend continued by Valeo's successors. Some notable secretaries A position of great trust and responsibility, the Senate secretaryship has been held by a long line of distinguished individuals. Samuel Allyne Otis, the first secretary of the Senate, had previously been speaker of the Massachusetts legislature and a member of the Continental Congress. Otis held the post of secretary for twenty-five years, never missing a day that the Senate was in session. General Anson McCook of New York, a former House member and one of the "Fighting McCooks" of the Civil War, served as secretary, as well
