Unfortunately, if it is a 3rd-party book, it is not available for Pathfinder Society.

If you check the description of the item, you can see if it is Pathfinder-3.5 OGL compliant or a Paizo Pathfinder book in the description.

In addition, there is also Additional Resources and Campaign Clarifications under the Pathfinder Society section of the site that can provide insight into what is valid and what is not.

Now that I think about it, surprised there wasn't such a thing in StarFinder (that I know of). Kind of a Sci Fi staple.
