National Archives Catalog

The National Archives and Records Administration (NARA) acquires, preserves, and makes available for research the records of enduring value that were created or received by organizations of the executive, legislative, and judicial branches of the Federal Government. Records in the custody of the National Archives date from pre-federal times to the present. Most of the records are textual, but they can come in a wide variety of media, such as microfilm, maps and charts, architectural and engineering plans, aerial photographs, motion picture reels, video recordings, sound recordings, computer data sets, or still pictures.美国国家档案与文件署（National Archives and Records Administration，NARA）负责采集、保存具有持久价值的档案，并向研究人员开放利用这些由联邦政府行政、立法、司法三大分支机构所生成或接收的档案文件。该署保管的档案时间跨度从联邦成立前直至当代，其中大部分为文本形式，但也涵盖缩微胶卷、地图与图表、建筑与工程图纸、航空摄影照片、电影胶片、录像资料、录音资料、计算机数据集以及静态图片等多种载体类型。
