Those are for a different format, called "OCTGN apprentice mode". OCTGN apprentice mode is a preconstructed format with all of the first 12 mages, ability cards and normal stats are used, 3x3 zone Arena, and 60 point spellbooks.
Well, the original idea behind these spell books aside, I think they're way better than the 50-point spellbooks for the official Apprentice mode in the core set. Especially since the ability cards and normal stats are used.
I've recently modified them for use as introductory spell books for Domination. Basically, I just replaced any promo cards and added one or two of the V'tar-related cards to each book (increasing point cost to 62).
I made a couple more adjustments to a few spell books because they seemed to include effects that had otherwise been avoided, i.e. 'Flying', and 'Familiar'.
I hope to be able to put them to the test this or next week.
