The Abhidamma Pitaka
Apologies for a nearly identical post to another question, but:

You can get a hard copy text of the Pali Text Society edition from:

The Pali Text Society: http://palitext.com
(they also have sets of the translations) Become a member and receive a nice discount.

You can find an on-line version of the BJT text at:
Metta Net Lanka:
http://www.metta.lk/tipitaka/index.html

You can get a searchable CD from the Vipassana Research Institute:
http://www.vridhamma.org/Chattha-Sangayana-CD-ROM-Update

These have the Abhidhamma texts.

EDIT: In response to your revised question. I have the Abhidhamma texts. The books are:
Abhidhamma Pitaka

Dhammasangani: Buddhist Psychological Ethics
Vibhanga: The Book of Analysis
Dhatukath¤: Discourse on Elements
Puggalapannatti: A Designation of Human Types
Kathavatthu: Points of Controversy
Yamaka: — 
Tikapatthana: Conditional Relations
Dukapatthana: —

I believe the book you have linked to is a new work constructed along the lines of the Abhidhamma. There may be others that can inform you better about that.
