It’s all about titles — the NBA Championship Title and book titles for the Cleveland Public Library and Boston Public Library.

Cleveland’s library arranged some books before Wednesday night’s win that spelled out the phrase:

“Cleveland Invasion, Boston … The Luck Runs Out.”

The Cavs beat the Celtics Wednesday night 117-104.

Boston’s library responded by stacking several book titles to say: “Never back down … the good fight continues … Friday.”

Cleveland takes on the Celtics again in Boston Friday for Game 2 at 8:30 p.m.
