The study of and the taste for collecting bookplates hardly date farther back than the year 1860. The first real impetus was given by the appearance of "A Guide to the Study of Book-Plates (Ex-Libris), "by Lord de Tabley (then the Hon. J. Leicester Warren M.A.) in 1880 (published in London by John Pearson of 46 Pall Mall). This work, highly interesting from many points of view, established what is now accepted as the general classification of styles of British ex-libris: "early armorial" (i.e., previous to Restoration, exemplified by the Nicholas Bacon plate); "Jacobean," a somewhat misleading term, but distinctly understood to include the heavy decorative manner of the Restoration, Queen Anne and early Georgian days (the Lansanor plate is Jacobean); "Chippendale" (the style above described as rococo", "tolerably well represented by the French plate of Convers); "wreath and ribbon, "belonging to the period described as that of the urn, etc. Since then the literature on the subject has grown considerably.
