I think the suggestions they created are backwards, personally. Given there are multiple sources to learn almost every spell in the book, being given the name of the spell without being given information on how to learn it would have been better.

That would let people test their memories and think "now where have I seen an enemy use this skill?" rather than have everyone going for the same few enemies. Even now because of the listings in the book, people are trying to get certain spells the hard way even though there have been found much faster or simpler methods of gaining the same spells (Eruption, Tail Screw, and Flamethrower come to mind as examples of this)
