In reply to jamie_bkc:
Yeah, as Jim said, you really want videos.
As a skier of many years blah blah I can't conceptualise that reading anything would help if you have never skied before.
Perhaps after a week or so you might read some tips and think 'ah yes, that might help.' But not initially, and certainly not for the core movement.
Good luck and have fun. I would strongly suggest an indoor snow place rather than a toothbrush dry slope. It will be less likely to injure if you fall and is more closely replicated to real skiing. Essentially you'll have more fun.
