I think that the most useful database for me so far has been Artstor. Artstor provides real, scanned pictures of American propaganda posters, among other images of art, which allows me to deduce similarities, differences and trends between different eras in American propaganda in relation to time spent in war and demographic the propaganda was intended for. I believe that this database has been the most helpful for me because I am interested in comparing propaganda created for World War II regionally, comparing propaganda from World War II to subsequent wars like the Vietnam war or looking at the affect that World War II propaganda had on art after the war. I’m not sure what form art specifically yet. This database is 100% visual, so I find it most helpful when arriving to my own conclusions regarding differences in time or region and the latter impact of WWII propaganda on specific forms of art.
