I noticed that loads of people ask for help and requests outlines and notes. Well, I found several sites where they let you view powerpoint presentations of theirs. All rights reserved to each site and their owners, so no stealing. ^^

This site has terms you should know:

Our class uses Ms Pojer's Powerpoints a lot and her powerpoints are really helpful. Her whole website is helpful. You can find sample DBQs her students did and their finished essay.

Well, I hope that helps. If you want me to find site for any particular book or anything, you may ask me. =D
