The collection consists of a manuscript account of the uprising Racconto della sollevazione di Napoli accaduta nell'anno 1647, written in 1740. Beginning in 1503, Naples was ruled by Spain through a viceroy. There was also a seggi or municipal administration which was dominated by the aristocracy, but did have a small popular representation. The uprising of July 1647 was provoked by the high cost of living and by taxes, and had as its figurehead a fisherman named Masaniello. It was in fact organized by Giulio Genoino, a lawyer who wanted the people's voice on the seggi to be equal to the patricians. The rebels attacked prisons and armories, looted the houses of the nobility, and lynched several people. After a few days, a settlement was negotiated by the Cardinal Archbishop

The Taylor White Collection is comprised of 938 watercolour paintings of mammals, birds, fish, and reptiles. White, a British jurist, commissioned various artists of the day (including Charles Collins, Peter Paillou, Jacob Van Huysum, George Edwards, and Eleazar Albin) to paint these animal portraits from live and dead specimens brought back to England from around the world. Many of the paintings are accompanied by loose-leaf manuscript notes, written mainly by White in Latin, providing further information about the animal; transcriptions and English translations of these notes have been provided within the record for each painting.

Family correspondence chiefly from 1763 to 1820 and family history documents.

The fonds documents John Mappin’s occupation as an independent antiquarian book seller, his personal interest in the history of print and Canadian politics, and his personal achievements as an author. The wide variety of subject files found in this collection are almost entirely North American based and span from 1733-2004. These records reflect Mappin’s particular focus on Canadian authors and Canadiana in general.

The Coppenrath Collection of Voyageurs Contracts for the North West Company partners contains 52 contracts for the period from approximately 1800 to 1821. These document the terms of engagement for men going into the North West . Voyageur contracts are of particular interest for study of the fur trade, Canada's first major industry, because they document the conditions of employment for many of the journeymen ("engagés") involved in the trade, both those who worked on the Ottawa River and those who "wintered" in the North West. The contracts are dated from 1800 to 1821 with printed forms from before 1800 being used in some cases. A significant number of outfitters are included namely the firm of McTavish, McGillivrays & Co. with various partners including John Ogilvy and Thomas Thain, Pierre de Rocheblave and earlier partnership – McTavish, Frobisher & Co. As well, there are contracts with lesser known outfitters. These contracts provide not only the names of the "engagés" but usually their place of residence and the conditions and terms of their employment.

This collection consists of legal documents concerning the settlements of the estates of Sir W. Chester, 1728-1730.

This fonds contains documents created by or created for members of the Hall family and their extended family, beginning with Sarah Barker and ending with Charlotte Anne Vennor Lindsay, her great-great-granddaughter. The documents in the fonds represent the personal relationships and activities of Hall family members, as well as some of their business dealings. They date from between 21 January 1719 and approximately 1912, with the majority of the documents representing the period between 1750 and 1890. The documents were created while members of the Hall family and their relations lived in Montreal, Quebec City, and in New England (including Philidelphia, Andover, and Boston). Other documents were created in parts of Ontario (including Kingston, Fort Erie, and York/Toronto) and Germany (Kirchbrak, Durlach).

The fonds is arranged into four series: Diaries, Correspondence, Financial and legal documents, and Other family papers. The Diaries series consists of bound diaries and loose diary entries created by Hall family members. The correspondence series consists primarily of personal correspondence between Hall family members, with some business correspondence and some letters and notes related to genealogy and a financial legacy. The Financial and legal documents series contains a variety of documents related to personal and household expenses, guardianship of minor children, land sale and management, and the execution of wills and distribution of estates. This series includes accounts, receipts and invoices, loans, power of attorney, land surveys, wills, inventories of estates, a marriage contract, and other documents. Finally, the Other family papers series contains documents that did not fit neatly with the other series. These are related to the Hall family's participation in military, religious, and masonic organizations - documented by certificates, official letters, and a religious manuscript - and also includes a recipe.

Leoni's manuscript of "Li cinque ordini dell'Architettura civile nelle Misre di Palladio con altri Studi..." was written in Dusseldorf in 1708, and illustrated with Leoni's own drawings. This treatise was never published.

M. Keith, Bernard Bolton, George Tucker and others, with sketches (1817); and Lady Murray's poetry commonplace-book (approximately 1820) containing poems by celebrated authors and some original pieces.
