Defense Bonds become War Bonds become Savings Bonds

I need to find out about War Bonds and Defense Bonds from 1941. Where I can I find more information? Tom's response First check out Herb Kugel's article on About.com, Home Front 1941-45: Buy War Bonds. Kugel's long article gives a complete picture of the early history of Savings Bonds. Then, just for fun, check out these images of War Bond posters maintained by the Northwestern University library.
