From the introduction: "This classification system embodies every effort to encompass the range of Jewish knowledge found in the kinds of published materials now located in libraries, ranging from books to the latest materials in electronic format. Although based on the familiar decimal organization, and to that extent tied to the canons of Western logic, the categories, their sequence, and the terminology employed to label them are drawn from Jewish tradition insofar as possible. This had meant the construction of a system 'from the ground up,' as it were, beginning with certain conceptions about the proper way to organize Jewish knowledge and the appropriate categories for its division."
