Are you sure you're talking about the same thing?

This article is about psychological patterns related to task management and productivity. The book you linked to seems about software messaging system design.

Apparently ues, because the OP gave exactly the same answer: he was talking about "pattern books" in general, and apart from this pdf and the original Alexander's book the absolute majority of "pattern books" (and articles) is about IT themes.

That's quite odd because such patterns and archetypes exist everywhere. It seems like quite a mathematical notion.
