The major record of the McGill Chapter's early years is a register containing members' signatures, 1911-1969, and minutes from 1912 to 1932; a second minute book covers the period 1960-1969. Approximately two-thirds of the papers are secretary's files from 1961 to 1978 containing membership lists, correspondence concerning prospective members, circular letters announcing meetings, and correspondence with the headquarters of AOA. There are also receipts for initiation fees from 1954 to 1969.

Fonds contains a volume of receipts for various supplies received by the financial official of the cathedral chapter of Pisa, the monastery of San Lorenzo, and by other religious houses and individuals. The volume was begun by Captain Antonio Fantoni.

The Society's bank book,1913-1925 and receipt book, 1924-1925, are accompanied by a newspaper account of its annual outing in 1889, and a photocopy of the notice of a meeting, 1890.
