Only available from ProQuest - it is not possible to receive treaties from the official publisher. ProQuest has collected (on microfiche) all treaties to which Canada has been a signatory power since 1928. Because of the irregular order in which treaties are issued, microfiche is the ideal medium for maintenance of backfile sets.

The following is a more complete breakdown of Canadian Treaties Series available from the Government Documents collection:

• Treaties: Treaties since 1975 appear on discrete microfiche, so that updates may be interfiled as they appear. Treaties are published only after ratification. This can be some years after the cover date. Indexes are compiled and published several years later.
• Department of External Affairs. Statements and Speeches: filmed from the collection assembled by the Departmental Library, these documents, originally published as press releases, are unavailable as a complete set in any other form. A full index, prepared by the Library, is also available.
