Meredith's papers relate almost exclusively to his professional, philanthrophic and leisure activities prior to his appointment as Dean of Law. The largest series comprises correspondence files (1927-1945) dealing with his professional expenses, memberships, insurance, investments, and personal finances. Other professional papers include files on the survey of the Legal Profession in Canada 1945-1946, and an address to the Junior Bar Association on automobile accident law (1945). The philanthropic aspect of his work is documented by files on the Inns of Court Fund, 1947-1948; and particularly on Bishop's University, of which Meredith was a trustee, 1943-1950. Meredith was chairman of the Québec Committee, the Selwyn House School Association, 1945-1948. Correspondence regarding amateur radio licencing, transmission, and equipment reflects Meredith's favourite hobby, 1945-1947. The only material relating to his teaching career is an introductory lecture to first-year students entitled "The Legal Profession".

The major component of Meredith's papers consists of 1 m of personal correspondence files, dating from 1903 to 1938, and is largely concerned with finances eg. memberships, purchases, and the liquidation of his mother's estate . The remainder concerns Meredith's Chancellorship of Bishop's University (1925-1938), and his introduction of a private member's bill (1926-1927) to have his son W.C.J. Meredith admitted to the Québec Bar on the strength of his Cambridge degree.
