Whatever title to intellectual distinction the future historian may deny to our time, its right to be called the age of encyclopaedias will hardly be challenged. We have general encyclopaedias on a scale almost Chinese and special encyclopaedias of every branch of learning, science, and art. No generation has put so much of its time—profitably or unprofitably—into co-operative enterprises for alphabetizing all knowledge. We have had within the last few years two large Bible dictionaries—one of them with two supplements; a Jewish Encyclopedia in twelve volumes; new editions of the standard Protestant encyclopaedia of Herzog-Plitt-Hauck and of the Catholic encyclopaedia of Wetzer and Welte-Hergenröther-Kaulen; the beginning of a great Catholic Encyclopaedia in English and of an encyclopaedia of Islam; and now the first instalment of an Encyclopaedia of Religion and Ethics, which will extend to at least ten volumes.
