Links, Code, Errata, and Contacts

I learned the hard way with the first edition that URLs change more quickly than a printed book can be updated, so rather than providing an appendix of URLs, I'll provide just one:

regex.info/

There you can find regular-expression links, many of the code snippets from this book, a searchable index, and much more. In the unlikely event this book contains an error :-) , the errata will be available as well.

If you find an error in this book, or just want to drop me a note, you can contact me at jfriedl@regex.info.
