The collection covers the political career of J.B. Murta from his first election to the House of Commons in 1970. One major focus of interest is the material relating to the Canadian grain industry, with its associated transportation problems. A second focus of interest is the correspondence with constituents and others on a range of issues. There is some information on Party organization and politics, including the leadership conventions of 1976 and 1983.

Not included here are the personal diaries of Mr. Murta which he has retained in his own possession for the foreseeable future.
