In this article the author discusses the evolution of the profession of librarianship and the compromise of educating librarians in schools instead of by apprenticeship. He poses a series of questions, some more rhetorical than others: (1) Is Technical Services an intellectual concept or an administrative device?; (2) Can the routines and rules of Technical Services be taught in school? Should they be?; and (3) What is the relative place of theory and practice in education? Throughout the article, he states his belief that attention is focused on practice and not theory. He believes it is important to begin teaching the profession with the basic techniques until they are mastered, and then it is important to focus on theory and devastating analysis.
