These works are divided into two collections. The or Québec heritage collection, with about one million works, consists of copies of all works given to the BNQ for legal deposit, that is every book published in the province since 1968 as well as some 35,000 books published elsewhere that are pertaining to the subject of Quebec or whose at least one co-author is originally from the province. Documents by or about French Canadians, French Americans or Aboriginal peoples of the province are also included in this last number. This is supplemented by the Saint-Sulpice collection of some 78,000 works, some dating back to the 1760s and including books from the personal libraries of such figures as Louis-Joseph Papineau and Louis-Hippolyte Lafontaine. The "Collection nationale" is available for on-site reference.
