Bookish Rogue Spell Book question

[Jeff Clem]

I'm playing a Rogue with the bookish rogue feat. Can a Rogue buy a Arcane spell book. We don't have a Wizard in a Sorcerer in the group.

Bookish Rogue
Thanks to your preparation, your arcane ability is more varied than most.
Prerequisite(s): Minor magic rogue talent.
Benefit: By studying a spellbook for 10 minutes, you can change one spell you are able to cast using your minor magic or major magic rogue talent to one sorcerer/wizard spell of the same level contained in the spellbook. This change is permanent until you take the time to change it via this feat again.

I don't see why not. Thieves guilds, poor wizards, spellbooks from dead casters all would be good story ways to get one.
