Blood flowed in a Brooklyn library Tuesday night when a man — enraged because another library user was viewing porn — stabbed him in the chest, fire and police sources said.

The 56-year-old homeless attacker, who was taken into custody, was with his wife on the second floor at the Brooklyn Heights Branch of the Brooklyn Public Library when he spotted the racy videos on the 52-year-old man’s screen around 7:20 p.m., police sources said.

“He was with his wife and he accused the other guy of looking at porn,” one police source said. “The guy looking at porn picked up a chair and hits him. The guy who was offended said, ‘I have a knife,’ and stabs him in the chest,” the source continued.

Then, the man’s wife started screaming, “How are we going to get back to Peekskill?” the source said.

It was not clear if the couple lived in Peekskill.

The victim, who was conscious and talking, was brought out of the library in a wheelchair, police sources said.

The wounded man was taken to Bellevue Hospital and is expected to survive the attack, police said.

Charges against the stabber were pending Tuesday night, police said.
