Here is a list of other references for this course (on reserve except for the last one). It is always useful to complement the textbook (TM) by reading other material.

• V.Barger and M.Olsson, "Classical Mechanics: a Modern Perspective": not as comprehensive nor technical as TM, but provides good physical insight and discusses interesting examples.
  
• H. Goldstein, "Classical Mechanics": a classic text, well written, somewhat different organization and emphasis than TM.
  
• V.I. Arnold, "Mathematical Methods of Classical Mechanics": nice if you like a rigourous formal presentation.
  
• James Gleick, "Isaac Newton": for your free time, nice historical account .
