To be absolutely insane beyond words. Since public libraries are open to all people from all walks of life they often become a second (first?) home for the mentally ill and paranoid. Public library crazy refers to people who talk gibberish and reek of urine and stale cigarette smoke. Public library crazy is the craziest form of craziness possible.
That homeless man who thinks the feds are after him like to hide in the restrooms at the library. He talks to himself and is convinced he is being spied on by Communists. He is indeed Public Library Crazy.
