The armorial bearings, stamped upon the back or sides of a book, or printed upon paper and pasted within the cover, were sufficient, without a name, to identify the family to which it belonged. Libraries descended from father to son, and were kept intact for generations; and the family arms and motto were the most appropriate label possible.
Warren, one of the first to study book-plates and to give to others the benefit of his researches, has divided the armorial plates into general classes, and has given them suitable names, which are accepted the world over. A considerable number of subdivisions has been made; and while they may be serviceable where book-plates are plentiful, they are but an incumbrance to the collector of the early plates of America, for our examples are few in number, and are quite sufficiently distinguished—for the purpose of the present work, at least—by the following styles: Early English, Jacobean, Chippendale, Ribbon, and Wreath. Distinctive, easily remembered characteristics pertain to each of these, and fairly accurate dates of their adoption and continuance can be given.
Adopting then the nomenclature of Warren, and following his lead, we come now to consider the meaning of the different styles and the diversity of their designs.
The very earliest class is the Early English, in which the shield of arms is present with all its accessories. In these plates the mantling is very profuse, and in large full-rounded curves surrounds three, and often all four, sides of the shield. This is the only ornamentation, nothing incidental being added as yet; the name of the owner is usually or often accompanied by a title and address, and quite frequently also by the date.
