   It's a good book to have.  It goes into depth on a lot of things that   
   other orbital-dynamics books just skim over.   
      
   The one disturbing note is that I've gotten one or two hints that he (or   
   his editor) is not as careful as he should be about proofreading stuff   
   taken from other people's papers.  Notably, his equation 9-57 (mean lunar   
   perturbation of perigee height) is simply wrong, as one can see by   
   consulting the original paper or the discussion in Wolverton's "Flight   
   Performance Handbook for Orbital Operations".
