The paperback and online versions of the book contain some errors, and the corrections to these versions are given below:

Repeatedly throughout the text: “an RR-VGLM” should be “a RR-VGLM”.

Page 555, Eqn. (A.50): the sign before the summation is “−” rather than “+”, i.e.,

$$\displaystyle\begin{array}{rcl} \psi (x)& \ =\ & \log x - \frac{1} {2\,x} -\sum\limits_{ k=1}^{\infty } \frac{B_{2k}} {2\,k\,x^{2k}}\ =\ \log x - \frac{1} {2\,x} - \frac{1} {12\,x^{2}} + \cdots \,,\ \ \ \ \ \ \ {}\end{array}$$
