For students who want to explore macroeconomics further, I have introduced the following two features:
- Short appendixes to some chapter, which expand on points
   made within the chapter.
- A further readings section at the end of most chapters,
   indicating where to find more information, including a number
   of key Internet addresses.
   
    Each chapter ends with three ways of making sure that the material in the chapter has been digested:
- A summary of the chapter’s main points
- A list of key terms.
- A series of end-of-chapters. “Quick Check” exercises are
   easy. “Dig Deeper” exercises are a bit harder, and “Explore
   Further” typically require either access to the Internet or the
   use of a spreadsheet program.
