David J. Hughes: Five Stars for the textbook Maintenance 

Dr Coetzee has written an excellent book on the subject. Having read many other books written by good authors such as Kelly, Jardine, Smith, Lyonnet, Campbell, Moore etc this is by far the best. If you want to learn some good theory, modelling and how to go about setting up a real maintenance system then this is the best book around.
