iTunes U for Primary Sources

I have used iTunes U in the past to listen to a few lectures on history, but it appears they have been doing some innovative work by adding a great primary sources catalog. The best thing about it is the ease of use and search. Most primary document vaults I have seen from government are not user friendly at all! I already got side tracked while writing this blog by one of my favorite writers of the 1800's, Lysander Spooner. You will need to use iTunes to open up the link and I have found that any PDF or book will open in your iBooks. Search and enjoy. Click here or just go to it in iTunes.
