The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)

Not only the lives of this century's presidents, but also the figures and events that surround them are covered by the works in this series. This particular volume covers the lives and times of Warren G. Harding and Calvin Coolidge. Thousands of books, articles and dissertations are cited and summarised in each of these detailed, accessible bibliographies. The contents are organised by topic to enable researchers to easily focus on broad or narrow areas of interest. The volumes also contain introductions assessing the presidents' places in history and detailed chronologies of their lives. Each chapter begins with an overview of the relevant literature and points out the key sources in different subject areas. All the volumes are indexed by author and subject.
