- Page 90, Line -1: The integral on the right-hand side is missing
a factor of . The equation should read

- Page 167, Algorithm 7.1:
- Line 10:
`T.Edges(eptr(2,2))`should be`T.Edges(eptr(2),2)` - Line 12:
`T.Edges(eptr(2,1))`should be`T.Edges(eptr(2),1)`

- Line 10:
- Page 172, Algorithm 7.5:
- Line 10:
`nonzero`should be`negative`

- Page 225, Chapter 10: This chapter fails to give any suggestions for
further reading about direct methods for sparse systems. An up-to-date
treatment that just appeared is
*Direct Methods for Sparse Linear Systems*by Timothy A. Davis (SIAM, 2006). - Page 334, Section 15.2: The explicit residual indicator described
in this section is due to Ainsworth and Oden (see Section 2.2 of
*A Posteriori Error Estimation in Finite Element Analysis*by Mark Ainsworth and J. Tinsley Oden, reference [2] in the bibliography). The citation was inadvertently omitted. - Page 338, Line -4: ``three-point element residual estimator'' should be ``explicit residual estimator.''
