I am currently studying the checks and balances between British and American Governments and found a great YouTube channel called Crash Courses.  It has subjects in all sorts of items such as history both world and European, politics and psychology and I have discovered so much more than reading just papers after paper.  If you or the kiddies need a funny, interesting and knowledgeable video to watch (I prefer to listen than to spend hours, hours, hours zzzzzz reading) then log onto YouTube and write Crash Courses and find out if there are courses for your requirements.  You won’t regret it.
