Understanding this stuff is key to deciphering how gold fits into the big picture of the global monetary system. So I'm going to lay a little knowledge on you.
Peter Bernstein's A Primer on Money, Banking and Gold is still one of the best books about this subject.
Here are some books about Bretton Woods, which was the international monetary conventions that lasted from World War II until the early 1970s and is still often referenced today.
Finally, Peter Bernstein's (again) delightful book is an overview of the history of gold in human affairs.
Hopefully this information will get you beyond the day to day of the market and into a deeper understanding.
