War of 1812 Digital Collection
The War of 1812 Digital Collection, from Canadiana.org, is a great portal for finding primary sources from the War of 1812. The database contains items from Early Canadiana Online, as well as items that have been submitted by partner institutions specifically for the bicentennial. The portal is searchable, and provides high resolution images that can be easily downloaded.
The portal will link you treasures, like this original copy of the Treaty of Ghent, and early biographies of key figures from the war, like Prevost, Tecumseh, and Fitzgibbon.
