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.
