The Cassius Marcellus Clay papers, spanning the dates 1842-1901; n.d., consist chiefly of correspondence from various 19^th century personalities to the American statesman and diplomat, Cassius Marcellus Clay, as well as various original documents such as Clay's passport, military commissions, and certificates. Among the correspondents are the following: Abraham Lincoln, William H. Seward, Harriet Beecher Stowe, Henry Ward Beecher, John Bigelow, Sir Andrew Buchanan, Simon Cameron, Salmon P. Chase, Charles A. Dana, Gustavus V. Fox, John C. Fremont, Prince Gortchacow, Horace Greeley, John Lothrop Motley, Carl Schurz, Edwin M. Stanton, Baron Edouard de Stoeckl, Charles Sumner, and Henry Watterson. The collection is arranged chronologically.

The bulk of the correspondence spans the years 1855 to 1886, comprised chiefly of incoming correspondence. The collection of correspondence and original documents was acquired by Lincoln Memorial University in 1936 from the Stewart Kidd Company, of Cincinnati, Ohio. The provenance is unknown.

Several of the letters were published in Clay's memoirs: The Life of Cassius Marcellus Clay: Memoirs, Writings, and Speeches …, which was first published in 1886. The majority of the letters in the collection are unpublished, with the exception of being published in microfilm format.

The Addendum includes the following material: a printed flyer, inscribed by Clay, entitled "Removal of the Capital: Call for a National Convention at Louisville, October 20^th, 1874;" a certificate issued by the State of Kentucky, Executive Department (Sept. 24, 1874), appointing Clay as a delegate to attend and represent Kentucky in the National Convention (1874); and a document issued by Governor McCreary (Nov.11, 1878), of the Commonwealth of Kentucky, appointing Clay a delegate to the Convention for the promotion of American Commerce; and a certificate of membership issued to Cassius M. Clay by the Audubon Society, signed and dated Aug. 21, 1886.

Collateral material is available in other related collections, including: the Seiberling Collection of material which includes an original scrapbook of newspaper clippings presumed to have been compiled by Cassius Marcellus Clay; various 19^th century biographical newspaper clippings; and several rare pamphlets. This particular collection was donated by the founder and first president of Goodyear Tire and Rubber Company: Mr. Frank A. Seiberling, a former trustee of Lincoln Memorial University.

Other Clay-related material is located in an artificial collection of assembled material: Cassius Marcellus Clay Collection, which includes contemporary newspaper clippings; photographs of Clay's estate, White Hall, before the restoration; various published articles, such as brochures and pamphlets; two letters of Brutus Junius Clay; and a handwritten note to Kentucky historian and author, Prof. Thomas D. Clark, by a namesake of Clay's (his great-nephew). The provenance of the items in the collection is unknown.

Brutus Junius Clay (1847-1932) was a son of Cassius M. Clay; he served as the U.S. Minister to Switzerland (1905-1910). The two letters of Brutus Junius Clay referred to above are both incoming correspondence from the following correspondents: David Jayne Hill (American diplomat, Berne, Switzerland), written Mar. 31, 1905; and John W. Kern (U.S. Senator), written ca. 1916. A handwritten note, not dated, of Clay's great-nephew and namesake, Cassius Marcellus Clay (1895-1959) is to be found in the same collection.

The Cassius Marcellus Clay Papers consist chiefly of incoming correspondence to Cassius Marcellus Clay; the correspondence is arranged chronologically. The majority of letters and documents are written in English; some are written or printed in French or Russian. A few documents, such as three Certificates of Commission (military) and a passport, are found within the series; additional documents are located in the Addendum.
