Search the forum...that said though the best thing you can do for yourself is find a decent coach - I personally wouldnt try teaching myself OLs. Most places will have little OL or PL clubs floating around, also if youre at university see if there is a OL/PL club or see if you can train with some other club where OL lifts might be used in training regularly (football?)
As to learning the lifts yourself: If you are midly athletic and are willing to spend some time thinking about what to do and how, I don't see an issue. Obviously, getting a coach is much better than learning alone, but if you can't find a coach, don't sweat it.
