The Bibliothèque et Archives nationales du Québec offers a valuable selection of digital music resources that might be easily overlooked. It's materials are not part of larger aggregates like the Internet Archive or Gallica. The catalog offers both materials that are part of the public domain and documents that can be accessed with an annual fee. At present the collection of free digital scores totals about 2,050 tiles, with a focus on French vocal sheet music and French opera vocal scores. The collection of digital audio files offers about 1,400 works, again with a focus on French vocal music. Public domain offerings also include a modest selection of opera librettos and several musical revues. Collectively these resource enable an interesting research perspective of opera and its related popular vocal music in Québec in the late 19th and early 20th centuries.
