Note from Bliss: "These files consist of virtually all of my ingoing and outgoing correspondence, beginning in the summer of 1967 when we moved to Harvard to be Claude Bissell's Teaching Assistant during his tenure as Mackenzie King professor of Canadian Studies there. The normal organization is simply by date - but my filing system has never been meticulous and many letters may be out of order [users are welcome to straighten them out by date], or may have slipped into other files in the collection. Some correspondence with particular colleagues and/or friends has been filed separately for some years. Some important letters or exchanges have been given separate files. The correspondence is highly professionel - with a wide range of Canadian historians and covering everything of interest to young historians - and also personal, containing correspondence with family friends and students, political letters [I was extremely upset about the Vietnam War, and wrote to various political figures] and many others.
The files relating to my editorship of the Social History of Canada series bet ween 1971 and 1976 could have been put in Series 3, but are included in this series because so many of the letters contain material of more general interest. As well, quite a bit of Social History material found its way into the general files, so they also go together for user convenience."
