Query: Handy and accurate

I find this book most useful for the 12 star maps found at the very begining. It gives basic information about astronomy in a comprehensible manner. The book is handy enough to keep with you and with a small penlight you can reference the maps while observing the night sky, easily fits in a jacket or pans back pocket. Additionally I found the mythology behind the traditional western culture naming of the constellations interesting.Only criticisms include 1) as previously mentioned, no star charts for the Southern Hemisphere and 2) wasted pages printing illustrations of the characters the constellations represent. These pages could have been used to add Southern Hemisphere maps or to discuss more then the listed 13 constellations.
