Hey John, it's Neil from SpellStorm (Zaresh the Mongoose, Kalitharston).
Any time you want to find out what books/items are legal: come to this site, click on the Pathfinder Society logo to the left. Then in the grey bar up top, you will see "Additional Resources"
That will give you the latest list of everything allowed for Pathfinder Society.
Everything there is strictly Paizo books, however. No 3rd-party books, including Wizards of the Coast.
