The papers of W.D. Lighthall are divided into a number of different series: an Original Series, Letters and Papers, 1881-1946, and a New Series, Letters and Papers, 1865-1954. The greater part of the correspondence is to be found in these two series. Correspondents include the following Canadian literary figures: Duncan Campbell Scott, Charles Sangster, Charles G.D. Roberts, W.W. Campbell and Stephen Leacock. Other represented in these series are Sir Wilfrid Laurier on political questions and Sir William Van Horne on artistic ones. Among other subjects covered are the McCord Museum, the Château de Ramezay, the McGill University Library, the Manitoba school question, conscription and imperial government.

There are series for the Canadian Authors' Association, the Metropolitan Parks Commission, the Great War Veterans' Association and the Royal Society of Canada. The papers of the Montreal Armenian Relief Committee (1920s) are included, as are the papers of secretary, George S. Wilson, of the Society of Canadian Literature, 1889-1890. There is some material on various legal cases in which Lighthall was involved including some Indian land claims. There is a series of personal financial records and some material on church union (ca. 1910). There is also a long series of documents, both originals and copies, dealing with the region of Huntingdon, Chateauguay and Beauharnois, Quebec. Most of Lighthall's literary works are represented in draft and / or annotated form including The False Chevalier (1898) and The Master of Life (1908). There is also Lighthall's index of Canadian authors' pseudonyms (ca. 1880- ca. 1900). Finally, the papers include the dossier of eighteenth-century documents on which Lighthall based his romance The False Chevalier. Among these is a transcription of extracts from the diary of Michel Chartier de Lotbinière (1723-1798).

In addition to this manuscript material, there is the Lighthall Special Collection of books. This collection contains some five hundred titles of works, including reprints, on metaphysics, history and Canadian poetry. Many contain Lighthall's annotations; others are inscribed to him by the author.

The objects designed by Nobbs and presently in the archive include furniture and fittings such as armchairs, tables, and a chandelier, and utensils and plasterwork, including plaster statuettes for war memorials and decorative plasterwork.

The subfonds contains papers of Percy Nobbs representing a portion of the architect's professional and personal records. Neither Nobbs and his associates' office files nor Nobbs's private correspondence are represented in their entirety. Existing office files are noted under the appropriate operation numbers in subfonds 1-5, as are photographs from the office records. The papers in this subfonds have considerable interest for the researcher, since they span much of Nobbs's adult life (between approximately 1895 and 1960) and illustrate the tremendous range of his activities.

The Archibald papers in the Canadian Architecture Collection constitute only a very small portion of the architects' professional and/or personal records, since the office records and the private correspondence of John S. Archibald and his associates are not represented in their entirety. The papers, given to the archive by Hugh Percival (Peter) Illsley, consist primarily of photographic reproductions and postcards of buildings in Europe. Also included with this original material is related information gathered over the years by John Bland dealing with different aspects of John S. Archibald and Charles J. Saxe's professional activities.
