By the way, as with all instuctional texts, you may want to supplement it with another - in order to get a richer understanding. Also, do not buy the old 1986 funky version, buy the newest edition with blue, yellow, black, and red on the cover (not the one with white and red).<br /><br />This is mostly for aethetic reasons... Hey, I am just that shallow.

<br /><br />On a serious note, however, the newer version has been edited extensively.
