The JPL Archives AtoM catalogue features only JPL content. Discover over 400 archival fonds spanning over 500 linear meters of rare and one-of-a-kind materials documenting Montreal’s Jewish history. Subjects range from education and labour to women’s rights, Yiddish literature, Canadian art, politics, religion, and more.

JPL archival records are found on the Canadian Jewish Heritage Network (CJHN), an online portal to Jewish heritage collections across Canada. Listings by other institutions include the Alex Dworkin Canadian Jewish Archives, the Montreal Holocaust Museum, the Ottawa Jewish Archives, and more.

The Special Collections are listed in the JPL Library's catalogue. Note that selecting filters like "Rare Books" or "Jewish Canadiana" in the "Shelf Location" field may be key to isolating a collection.

JPL archival records are found on the EHRI portal, which offers access to information on Holocaust-related archival material held in institutions across Europe and beyond.

The William Ostreger Audio Collection preserves hundreds of original recordings of Jewish authors, intellectuals, and artists who spoke at the Jewish Public Library from the 1950s to the 1980s, capturing voices such as H. Leivick, Kadia Molodowsky, Abraham Sutzkever, Isaac Bashevis Singer, Irving Layton, Mordecai Richler, and Salo Baron. Begun by JPL board member William Ostreger in 1951—who recorded roughly 500 events—the collection was continued by library staff and now features talks and interviews in English, French, Hebrew, and Yiddish, with a selection available online through the Yiddish Book Centre.

The Henry Rabin Yiddish Talking Books Collection, launched by the JPL in the 1980s, features Montreal’s native Yiddish speakers— including board members, volunteers, and staff—reading classics of Yiddish literature for sight-impaired listeners. Inspired by supporter Shmuel Rosenberg, whose wife Rose had lost her vision, the recordings were made in a JPL basement studio by Henry Rabin, and are now available online through the Yiddish Book Centre.
