Newman's written works are wide ranging and of interest to scholars of many backgrounds. History, philosophy, literature, education, biography and theology are among the themes he treated in the many volumes he published.

His architectural taste has left us a magnificent legacy of buildings he designed. Musical and poetic expressions pervaded his entire life and work. Newman's philosophical cast of mind was unique. The compositional and stylistic quality of his writings has long confirmed his reputation among students of English literature. James Joyce said that "the greatest prose writer was Newman."
