The document summarizes Oklahoma's criminal syndicalism law passed in 1919 that made it a crime to publish, distribute, or display books advocating criminal syndicalism. It could result in 10 years in prison and a $5,000 fine. The law also made it illegal to organize or join groups that taught these doctrines. The document then discusses the book "Books On Trial" which recounts a police raid of a bookstore in Oklahoma City for violating this law, the arrests of customers and affiliates, and the subsequent trials of those arrested challenging the constitutionality of the criminal syndicalism law.
