==============
p. iv           order of authors' names

p. 14-5         all occurrences of 0.123456E-4 and 0.120000E-6 should be
                0.123456E-3 and 0.120000E-5, respectively

p. 20           limits on sums should be n = 1 to N, not 0 to N  (5 places)

p. 29           In Exercise 1.17 the formulas for hat s_m and hat c_m have
                the wrong sign when first introduced; the text should read
                "... are computed incorrectly as ... = ... - ... and
                ... = ... - ...".

p. 34           The superscript (k) on b_i in the last line should be (2).

p. 35           The first term in the first equation of (2.9) is missing
                an x_1 factor.

p. 37           27 should be 2 in first line of "one step of elimination"

p. 38           In the final displayed equation there should be an x_j
                factor in the summation just ahead of the ).

p. 87           at bottom, Figure 3.6 and Figure 3.7 should be 3.5 and 3.6.

p. 114          in Example 3.11 reference to Figure 3.2 should be Figure 3.5

p. 150          in Exercise 4.8  "approximation to x" should be "... y"

                       a      (a+b)/2      b

                          + epsilon^2 x^2 / (x-1)^2
                The last quantity becomes infinite as x approaches 1
                from the positive side.

p. 256 (2.4c)   x_1 = 38 or 39 depending on assumptions made.
