Well most people will just link you around to spots were you can read. Also "white", "black", "negative", "positive", "destruction", and or "creation" magick is only subjective names. Magick is energy and only energy. Whether it's "good" or "bad" is in the intent of the caster.
If you cast a spell on a person without them knowing it could be concidered "black" magick. Anyways, if you are going to begin you the arts of magick, I suggest you start from the beginning with is learn what magick really is, and how it is used.
Learn how to center and grounding energy..learn about the moon phases, those are always fun to learn about.
