“The U.S. Government Publishing Office (GPO) is digitizing historic volumes of the Congressional Directory from the 19th and 20th centuries. The first release includes Directories from 1869–1888, as well as 1993. Additional digitized historic Congressional Directories will be released on GovInfo as they are completed. Historically, the Congressional Directory has been one of the most comprehensive and detailed resources for identifying the components of the three branches of the Federal Government. It includes short biographies of each member of the Senate and House, as well as terms of service and contact information for members of Congress. In addition, it provides descriptions of various Executive branch departments and Judiciary information. The public can now access these historic Congressional Directories on GPO’s GovInfo, the one-stop site to authentic information published by the Federal Government, free of charge.” https://www.govinfo.gov/app/collection/CDIR
