I've bought and begun reading the book mentioned in this article, and it seems like this article is simply a summary of the book - complete with intensive quotes (MOST of the article!)

I'm a little disappointed with the book so far - I'm extremely disappointed by this "article".

Another article by Shalveena about commonplace books and how best to use them.

Spoilers: They put a chronological table of contents in the back of the book. A really good idea!
