Nice work on the reseach! There is also "fair use" and that means that a reasonable use of limited amouts of some copyrighted material without permission from the orignal author is legal. Also, antyhing that is a direct quote from a history book or US Government work is usable without permission. It is just important to remember that it is bad form to use the work of others without crediting them for there efforts, copyright or no copyright.
