The Dynamics of General Relativity by Richard Arnowitt and others (1962 chapter; 2004 author reprint, arXiv:gr-qc/0405109)

Original chapter 7, pp. 227–264, in Gravitation: an introduction to current research. Author reprint: arxiv.org/abs/gr-qc/0405109

Section 5.1, equations 5.1–5.2, reprint p. 16: asymptotic energy and momentum surface integrals. Section 5.2, reprint pp. 16–17: coordinate invariance and Lorentz four-vector interpretation. The paper's gravitational-unit normalization differs from the conventional factor 1/(16 pi) in geometrized units.
