Let it be remembered that but a small part of the many books published have a permanent value, and that a book once eagerly sought may outlive its usefulness, and come to have a commercial value of so much a pound as old paper, instead of so much a copy in different styles of binding. Surely, no one can quarrel with the collector who removes the book-plate, found within it, from such a worn-out specimen, even if the removal necessitates the ruin of the cover. But to remove a book-plate does not necessarily mean to ruin the cover; it requires some skill and considerable patience to remove a valuable plate without injury to either itself or the cover upon which it was pasted, but it is done daily. Surely no one can find fault with this--a skilful operation resulting satisfactorily to the plate-collector and to the book-owner. [Illustration: Samuel Elam.] Again, no intelligent book-plate collector will separate the plate of a famous man from the book which has been its home for years, and which was once handled and read by its famous owner. Even a worthless book will thus be saved by the collector, which was fit but for the fire or the ash-heap, and which would have gone thither, plate and all, save for his discriminating eye, while a valuable book no one would think of despoiling. Would an intelligent collector, having a book from the library of George Washington, with his plate upon the cover and his autograph in its accustomed place, think of soaking off the plate and cutting out the signature? Not at all; no matter how worthless the book might chance to be, the fact that it was Washington’s is sufficient to insure it from any harm, while the presence of the autograph and the book-plate but adds to the value as establishing beyond peradventure the original ownership. The book-plate collector is naturally a book-lover. He must not be accused or suspected of crimes against his own kith and kin. He is a harmless and useful specimen of the _genus_ collector, who with assiduity, perseverance, and intelligence seeks to preserve these memorials of past days, which in the rage for indiscriminate collecting were overlooked, and are but now beginning to receive the attention they are worthy of.
