Explanation of errata
An erratum tells you where to find an error and what correction should be applied.
Details are provided below using an example from Generalized Linear Models
and Extensions.
The erratum below shows that for the first printing of
Generalized Linear Models and Extensions, a space needs to be removed
from the equation logit (z) = ... to produce logit(z) = ....
You can find the error on page 107, equations 10.6 and 10.7.
| (1) |
Chapter 10, p. 107, section 10.4, equation numbers 10.6 and 10.7
|
|
logit (z) = ...
|
logit(z) = ...
|
|
= -logit (y)
|
= -logit(y)

An erratum has two parts.
- The first line of the entry tells you where to find the error.
- The first item of the first line (in parentheses) tells the printing
number(s) for which this erratum applies.
(Click here to learn how to
determine the printing number of a book.) If your book is a later
printing number than that mentioned, you can ignore the entry. The
word “all” will appear instead of a number if the erratum
applies to all printings of the book.
- The second item on the first line tells you which chapter the
erratum applies to. Above,
the error is in chapter 10 of Generalized Linear Models and
Extensions.
- The third item on the first line gives the page number for the
correction (p. 107 in the example above).
- The first line of an erratum entry ends with more information
to indicate where the error can be found. The example above
directs you to section 10.4, equation numbers 10.6 and 10.7.
- The second part of an erratum entry is below the first line of the
entry and tells you what correction should be made. This information
can appear in several formats depending on the error.
- The most common form of an erratum is for changes. These are
shown with the
error in the left box and the correction in the right box. The example
above follows this format, and you can see that an extra space was put
between logit and the opening parenthesis. Sometimes a clarifying note
will precede the listing of the change.
- If something is to be deleted, a note to that effect
will be shown.
- If something is to be added, a note will indicate where to make the
addition, which will be shown in a box.
- If a correction is complicated or large, a note will provide a link to
the correction.
- If there are many corrections in the same section and
on the same page, the corrections will appear one after another within
the same erratum entry.
