Pierce Butler is considered one of library science's greatest intellects. His ideological conflicts with Douglas Waples, social scientist par excellence, became legandary in the 1940s. A humanist himself, Butler initially supported the introduction of social science methods in his seminal Introduction to Library Science (1933), which is reprinted in this volume. Yet he recanted this position late in life, and his critique of American librarianship was that it was becoming scientistic. He argued for something more—a deeper, more spiritual librarianship. In this biography, Richardson provides a well-documented narrative of Butler's life, with appendixes including a complete list of Butler's publications, course offerings, graduate students, and selected sermons.
