To help teachers better utilize Preserving American Freedom specifically and primary sources in general, we have also created a series of short podcasts.  These podcasts include interviews with the historians who wrote contextual essays, hints from a classroom teacher on using the website, and guidelines for how teaching with the website meets Common Core.
