A new website has recently come to my attention: it is CanadianLetters.ca. It contains copies of many letters written during the wars Canadians have fought.
Started by the History Department of Vancouver University and The University of Western Ontario, it's objective is to "let Canadians tell their own story in their own words and images by creating a permenent online archives which preserves Canada's wartime correspondence, photographs, and other personal material materials, from the battlefront and the home front".
Currently, they have letters from the Pre-1914 Era, First and Second World Wars, the Korea Collection, Post-Korea Collections, and an area called "Special Collections' which has interviews and newspapers like the Cobourg World, which published letters written home from the front in the First World War.
The project is ongoing, and as the website says, "It is continually seeking and adding new materials to the project site".
