advertise himself as a blockhead. Some of the commonest blunders are stamping on the back the translator's or the editor's name, instead of that of the author of the book; putting on adjectives instead of substantives for titles; modernizing ancient and characteristic spelling, found in the title, (the exact orthography of which should always be followed); mixing up the number and the case of Latin titles, and those in other foreign languages; leaving off entirely the name of the writer; and lettering periodicals by putting on the volume without the year, or the year, without the number of the volume. "No one but an idiot", said Mr. C. Walford to the London Librarians' Conference, "would send his books to the binder, without indicating the lettering he desires on the backs." The only safe-guard is for the librarian or owner to prescribe on a written slip in each volume, a title for every book, before it goes to the binder, who will be only too glad to have his own time saved--since time is money to him. I would not underrate the book-binders, who are a most worthy and intelligent class, numbering in their ranks men who are scholars as well as artists; but they are concerned chiefly with the mechanics and not with the metaphysics of their art, and moreover, they are not bound by that rigid rule which should govern the librarian--namely--to have no ignoramus about the premises. In writing letterings (for I take it that no one would be guilty of defacing his title-pages by marking them up with directions to the binder) you should definitely write out the parts of the title as they are to run on the back of the book, spaced line upon line, and not "run together." I think that the name of the author should always stand first at the head of the lettering, because it affords the quickest guide to the eye in finding any book, as well as in replacing it upon the shelves. Especially useful and time-saving is this, where classes of books are arranged in alphabetical sequence. Is not the name of the author commonly uppermost in the mind of the searcher? Then, let it be uppermost on the book sought also. Follow the name of the author by the briefest possible words selected from the title which will suffice to characterize the subject of the work. Thus, the title--"On the Origin of Species by means of Natural Selection", by Charles Darwin, should be abbreviated into Darwin -------- Origin of Species.
