Historians, educators, and students with an interest in Canadian and North American history should check out the vast collections of Canadiana Online. This still-growing digital archive contains more than 25 million pages representing over 200,000 publication titles, the majority of which were published prior to 1921. From the main page, visitors can easily search and explore Canadiana Online's three primary collections: Monographs, Serials (which includes newspapers, magazines, city directories, and more), and Government Publications. Each collection can be browsed and searched individually, and users can also conduct keyword searches of Canadiana Online's entire holdings at once via the large search bar at the top. Users can also refine their results by searching within fields (e.g. subjects and full text) and filter results by date range and language. While publications in English and French make up the largest portion of the collections, there are also items in many other languages such as German, Latin, and Cree. The entire site is also available in French. Canadiana Online launched in its current form in 2018, following the merger of Canadiana.org and the Canadian Research Knowledge Network, during which it absorbed the now-closed Early Canadiana Online collections.
