I read Texas Obscenity Penal Code 43.21-43.23 on https://statues.capitol.texas.gov/Docs/PE/htm/PE.43.htm#43.21 and discuss its ramifications here. I reference the Nolo book "Legal Research: How to Find and Understand the Law" and the Jello Biafra spoken word album "High Priest of Harmful Matter: Tales From the Trial."
