Scouting with the iPod Touch - U.S. Historical Documents

U.S. Historical Documents
As a counselor for Citizenship in the Nation merit badge having the Constitution and Declaration of independence close at hand is helpful. (Note that there are free applications for both but they lack the note making and bookmarking capacities of this app.)

U.S. Historical Documents contains over 200 of the most influential documents in U.S. history with powerful search, note making and bookmarking abilities.

I have the basic ($.99) version but a 'pro' version ($4.99) features email capabilities and a paragraph 'slider'. 

Available from Standard Works through iTunes.
