   • 1976, Template:W (editor), The Mathematical Papers of Isaac Newton, Volume 7: 1691-1695, Template:W, page 3,

     Craige was then on the point of publishing a short tract wherein he expounded a systematic (if far from general) 'Method of determining the quadrature of figures comprehended by straight lines and curves',^{[editor's translation]} there gathering a variety of techniques of rational algebraic quadrature and arc-rectificationTemplate:....

3. Template:Lb The calculation of a definite integral by numerical means.
   • 1992, Bernard Bielecki, SINC Quadratures for Cauchy Principal Value Integrals, T.O. Espelid, Alan Genz, Springer, Numerical Integration: Recent Developments, Software and Applications, page 81,

     Three types of SINC quadratures are surveyed for the evaluation of Cauchy principal value integrals $\underset{\mathrm{\Gamma }}{\int }F(t)dt/(t-x)$, $x\in \mathrm{\Gamma }$, where $\mathrm{\Gamma }$ is an arc in the complex plane. Under suitable assumptions on F, the quadrature errors are of order $O(e^{-c\sqrt{N}})$, where N is the number of quadrature nodes and c is a constant independent of N.
