From the reviews of the third edition‎:‎ ‎"‎This is the third edition of a book that is already familiar to those who teach an introductory course in general relativity‎.‎ ‎.‎‎.‎‎.‎ Important concepts are introduced slowly and carefully‎,‎ so that the resulting text is a comprehensible first introduction that is suitable for both physics and mathematics students‎.‎ ‎.‎‎.‎‎.‎ its strength is that it is a short introduction to the subject that still covers all the essential material for a first course and provides a sound basis for further study‎.‎‎"‎ ‎(‎J‎.‎ B‎.‎ Griffiths‎,‎ Mathematical Reviews‎,‎ Issue 2006 h‎)‎ ‎"‎This book is a well‎-developed introduction to General Relativity‎.‎ ‎.‎‎.‎‎.‎ the present third edition is really re‎-worked in many places in comparison with the previous ones‎.‎ ‎.‎‎.‎‎.‎ Three appendices are quite helpful ‎.‎‎.‎‎.‎ ‎.‎ Solutions to the exercises‎,‎ References and Index close this very readable book‎.‎ ‎.‎‎.‎‎.‎ Every chapter ends with a list of problems ‎.‎‎.‎‎.‎ ‎.‎‎"‎ ‎(‎Hans‎-Jurgen Schmidt‎,‎ Zentralblatt MATH‎,‎ Vol‎.‎ 1089 ‎(‎15‎)‎‎,‎ 2006‎)‎
