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)

Lambert provided valuable descriptions of the general history of the area and various towns, detailed specific events, and discussed numerous facets of early American life: religious, political and social. There is a poem, entitled "Old Milford," taken from the Connecticut Gazette, Vol. I, No. 4, 1835, as well as a "History of Milford, Connecticut," written by Lambert in June, 1836 for Historical Collections of Connecticut by John W. Barber. Neither the poem nor the sketch of Milford appears in the printed version.
