Above is an excellent chart key for reading the symbols and glyphs we put up in every chart.  It is from Winstar Express, the most inexpensive astrology product out there at $59.00 from Matrix Astrology. 

I have used it for about 3 years now and it has helped me immensely the help section is ok but it comes with a few Michael Erlewine ebooks to help you along.  If you get it, upgrading to one of the big packages like  Kepler or Sirius, gets you a $50.00 discount; I recently did that which worked out well.  Shipping is about $11.00 extra.
