This article is not about lifting but it has some very good descriptions of different ways to bend. Before I had trouble grasping the proper way that the hips and knees are supposed to work together to let your back stay flat.

DD,

If you find that intriguing and/or thought provoking, I'd point you to the book "Starting Strength" (there's a cheap kindle version available). It goes into the kinematics of each of the lifts, describing the lever/fulcrum interactions of the kinetic chain (bones and muscles) used in each of the major olympic lifts. A very detailed and data rich tome of information.

Or, if you're more into watching some videos on the subject, I'd recommend perusing some of these:
