The collection consists of bound genealogies of Prince Edward Island families compiled by individual researchers. These are arranged alphabetically by family name.

The collection was originally accumulated by the PEI Museum and Heritage Foundation and the PEI Genealogical Society. The volumes included are generally donations from individual researcher/authors. The collection was transferred to the Public Archives and Records Office on 12 November 1992 when the Genealogy Division of the PEI Museum & Heritage Foundation was transferred to this office. Similar volumes will continue to be accepted and added to this collection.

This fonds consists of 18 reels of microfilm containing genealogical and historical material concerning Prince Edward Island which was gathered by George Leard to be used in the writing of several books on Island history. Reels 1 - 11 contain genealogical information arranged alphabetically by surname. Reel 12 -15 as well as Reels 1a, 2a, and 3a contain information, arranged alphabetically by subject, concerning communities such as Souris, Charlottetown, and Summerside.

This fonds consists of manuscript, typescript, and printed materials, in French and English, either created, received, or collected by Dr. J.-Henri Blanchard, including his writings and speeches, correspondence (almost exclusively incoming), research notes and documents in history and genealogy; agendas, minutes and other records of Acadian and generally francophone cultural organizations; maps, photographs, and printed materials. The arrangement into 9 lettered and titled series is based on a scheme inferred to be that of Dr. Blanchard, which comprised eleven untitled subdivisions lettered A to K; the letter designations appear to have had mnemonic significance in French. (The present arrangement combines in one series groups I, J, and K, all containing printed/published materials collected by Dr. Blanchard and without apparent distinctions between them.) The 9 series are: A: Articles/coupures = Articles/clippings, B: Biographie/généalogie = Biography/genealogy, C: Correspondance = Correspondence, D: Documents/données = Documents/data, E: Église = Church, F: Francophonie/ formation = Francophone education/culture, G: Géographie/cartes = Geography/maps, H: Photographies Photographs, and I: Imprimés = Printed materials.

The collection formed the basis of the reference library in the MacNaught History Centre and Archives Reading Room when the material was purchased from book dealer Laurie Bell. Wyatt Heritage Properties manager Allan Rankin and archivist Faye Pound arranged the transaction thus creating the core reference library.

The collection consists of 155 books or booklets, some of them considered to be rare. There is a 1770 textbook on navigation, a P.E. Island Calendar 1864, and a copy of MacKinnon and Warburton's Past and Present of Prince Edward Island. The collection is also comprised of thirty PEI telephone directories from 1963 to 1999. There are four 1903-1904 issues of the PEI Magazine, a 1943 Year Book of Registered Motor Vehicles, a Montreal Star WWI war map, and a 1963 promotional booklet on the village of St. Eleanors. The collection also contains a minute book from the Mount Pleasant Women's Institute, dated 1922-1937.
