This series contains voluminous correspondence on almost all issues brought before the U.S. House of Representatives during the 88th and 89th Congresses, 1963-1966. The folders, arranged alphabetically by subject, contain letters from White's constituents, copies of his replies, printed copies of legislative bills, copies of statements presented before Congressional committees, pamphlets sent to White by organizations or constituents, and occasionally White's notes on meetings with other members of Congress.

There are many types of correspondence, individual letters, mimeographed form letters, and pre-printed postal cards. Most letters are requests to White to vote a certain way on a particular piece of legislation; often organizations would write thanking White for his support of legislation which was favorable to them. White frequently referred letters which expressed strong interest in or opinions on bills before Congressional committees to the committee chairmen who would often respond detailing committee progress on the bill. This correspondence also forms part of the collection.

Since a Congressman receives mail from so many people it was deemed impractical to keep a complete name file of all correspondents, although a partial file was maintained for organizations and correspondents who wrote on many subjects. Likewise a file was maintained for the miscellaneous and legislative material found in the folders.
