Thanks for the link.

I abstained from registering, so I haven't read it. But from the

2. Awk in Action
2.1 Personal Computation
2.2 Selection
2.3 Transformation
2.4 Summarization
2.5 Personal Databases
2.6 A Personal Library
2.7 Summary

3. Exploratory Data Analysis
3.1 The Sinking of the Titanic
3.2 Beer Ratings
3.3 Grouping Data
3.4 Unicode Data
3.5 Basic Graphs and Charts
3.6 Summary

Reorganized chapter: 6.6 Recursive-Descent Parsing
7.6 A Recursive-Descent Parser for Arithmetic Expressions
7.7 A Recursive-Descent Parser for a Subset of Awk

Relocated chapter: Ch. 2 "The AWK Language" went to
Appendix A: Awk Reference Manual

I cannot see whether the chapter texts changed or have been expanded.

They have. For example, chapter 3. Exploratory Data Analysis, contains
"3.1 The Sinking of the Titanic" and "3.2 Beer Ratings", as well as "3.4
Unicode Data".

Sorry -- PDF pages != print pages; 2nd edition on publishers wedsite
says "240 pages" for the print edition.

I listed ch.3 under [completely] "New chapters" in this new edition.

My [old] edition doesn't seem to have that chapter "Exploratory Data
Analysis" at all. - What is this "1st edition"?

Do I have a "0th edition" then?

From the "Contents" page I can only see new or reorganized chapters.

Of course the page counts of editions likely differ, whether PDF or
print, since there are completely new chapters (and also relocations
and reorganizations of chapters).

In my initial post I wrote:
"I cannot see whether the chapter texts changed or have been expanded."
and what I meat was the texts of the previously _existing_ chapters;
whether they have been enhanced, corrected, rewritten, whatever, or
just copied. I cannot see that.

Looks like they did a bit of both (I've got an epub of the pre-release
of the new/2nd edition as well as a print copy of the original/1st edition).
