Sorry to hear that. I wondered how you could lose your co-authorship of Camel in the new edition. After all, parts of II are incorporated in III. If you wrote any of those parts then someone has violated your copyright.

But I am sure you know all that.

Unfortunately, there may be nothing you can do about it. Those of us on this forum will eventually get the word, and we will think less of O'Reilly than we would have otherwise.

Clearly no one is going to boycott O'Reilly. They do a lot for Perl that they need not do. But some of the goodwill that they earned gets used up in incidents such as this one.
