The book includes a scale compendium that includes all 1,749 scales, every scale Allan would’ve logged. That is, every 5, 6, 7, 8, and 9, note scale that is possible within the chromatic scale.
 
You also get the scales with the 4-semi-tones or less removed just the way Allan did it. That totals 1,307 scales. You will also get 217 parent scales with names for each one.
 
There is also a Holdsworth line compendium the lines are categorized by scale. There is a voicing compendium; these are voicings from Allan’s tunes. There is also a Messiaen voicing compendium. These are not Messiaen's voicings but voicings I found intervallic structures for and walked through each of Messiaen's Seven Modes of Limited Transposition using Allan’s approach.
