- Edwin F. Taylor and John Archibald Wheeler, Exploring Black Holes, Addison Wesley Longman, 2000. An elementary introduction to the relativity of black holes, using
line elements. Not easy to read, but worth it.
- James B. Hartle, Gravity, Addison Wesley, 2003. An “examples first” introduction to general relativity, discussing
applications of Einstein's equations before presenting the mathematics behind
the equations.
- Ray d'Inverno, Introducing Einstein's relativity, Oxford University Press, 1991. An excellent introduction to general relativity, which also covers
some topics not usually seen in introductory texts.
- David McMahon, Relativity Demystified, McGraw Hill, 2006. An abridged treatment of relativity, containing a remarkably complete
collection of formulas and topics, without much derivation. A useful
reference.
- Sean Carroll, Spacetime and Geometry: An Introduction to General Relativity, Addison Wesley, 2004. An excellent traditional but somewhat sophisticated introduction to
general relativity.
- Bernard F. Schutz, A First Course In General Relativity, Cambridge University Press, 1985. A good, easy introduction to the basics of both tensors and general
relativity.
- Charles W. Misner, Kip S. Thorne, John Archibald Wheeler, Gravitation, Freeman, San Fransisco, 1973. The physicist's bible of general relativity. Exhaustively complete.
- Robert M. Wald, General relativity, University of Chicago Press, 1984. The best available introduction to general relativity for advanced
students, but uses sophisticated notation (which has become the standard for
researchers in the field).
- Rainer K. Sachs, General relativity for mathematicians, Springer, New York, 1977. A very pure mathematical treatment of general relativity. Requires a
strong background in differential geometry.
