question about spell books

[Joe dirt]

can a wizard that finds or defeats another wizard use their spell book to prepare spells? or does the wizard need to spend money and resources to transfer the spells to his current spell book from the captured book first?

The Wizard can't use another caster's spellbook. He needs to spend money and resources to transfer into his current spellbook first.

Yes. This. The fluff is that each wizard encodes their spells into their own notation (or simply has very poor handwriting) and any other wizard who wishes to understand the spell must spend time and resources to decode it.
