## Abstract

Convergence results are proved for sequences of interpolatory integration rules for Cauchy principal value integrals of the form $$\not{\int}^1_{-1} k(x)(f(x)/(x - \lambda))dx,\quad -1 < \lambda < 1,$$ when $f(x)$ is singular at a point $\xi \neq \lambda$ and the singularity is ignored or avoided.
