Shallown said:YOu can memorize spells I am pretty sure but you have to make a Spellcraft check DC is like 15+ spell level I think. If you fail the slot stays empty.
Sorry not much of a rules expert.
I'm afraid that you can only prepare a spell from another wizards spellbook if it's a spell that you have already copied into your own spellbook at some point in the past.
It does take a spellcraft check with a DC 15+ spell level
