Biographical Directory of the United States Congress
American biographical dictionary

The Biographical Directory of the United States Congress (Bioguide) is a biographical dictionary of all present and former members of the United States Congress and its predecessors, the Continental Congress and the Confederation Congress. Also included are Delegates from territories and the District of Columbia and Resident Commissioners from the Philippines and Puerto Rico.
The online edition has a guide to the research collections of institutions where a member's papers, letters, correspondence, and other items are archived, as well as an extended bibliography of published works concerning the member (a shorter bibliography is included with the member's biography). These additional resources, when available, can be accessed via links at the left side of the member's page on the website.
History
Charles Lanman, author, journalist, and former secretary to Daniel Webster, gathered the first collection of biographies of former and sitting members of Congress for his Dictionary of Congress, published by J. B. Lippincott & Co. in 1859. Lanman intended his Dictionary of the United States Congress to serve as a guide for sitting Members of Congress, similar to the modern Congressional Directory.
In 1864, the House of Representatives and the Senate approved the publication of an updated version of Lanman's Dictionary of Congress by the new Government Printing Office. In the late 1860s Congress offered Benjamin Perley Poore, a journalist and clerk of the Senate Committee on Printing and Records, the job of preparing a Congressional Directory with biographical sketches and the kind of reference information found in the Dictionary of Congress.
In anticipation of the centenary of American independence and in search of a market not served by Poore's Congressional Directory, Lanman prepared the Biographical Annals of the Civil Government of the United States, published by James Anglim of Washington, D.C. in 1876.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Biographical Directory of the United States Congress”, the useful work is to connect “american biographical dictionary” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 16, 2026. The linked authority identifier is Q1150348. None of the 2 selected statements returned an explicit reference. The first chronological checks are 1859, 1864 and 1876.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
