Could you be thinking of a book chapter? This is one of the references from wikilpedia.
Misner, Thorne and Wheeler ("MTW") Gravitation (Freeman, NY, 1973), chapter 39: "Other theories of gravity and the Post-Newtonian approximation"
Cheers,
Pat

Subject: [Phys-l] An introduction to MTW?
I have a memory of an article (perhaps in AJP, perhaps 50pp?) that provided an introduction for physics students wanting to tackle Misner, Thorne & Wheeler's "Gravitation", giving extra help to get started.
An hour's worth of searching hasn't turned it up. Anyone remember this one? Any pointers?
