But the whole library should be an object-lesson of high educational value. A large, well-organized collection of books, especially if the public be admitted to the interior, is a graphic example of method and order, not to mention the enormous increment of value given to any stock of material by systematic indexing. The art of classification is not only an excellent mental discipline, but may be applied with advantage in every province of business and life. Though a classification of books is not the same thing as a classification of things, and may depart widely from the exactness of logical theory, there is no better way of inculcating the benefits of system than by allowing the reader to find his way from shelf to shelf, and follow the tracks pointed out for him to other book-cases the contents of which are more distantly connected with his subject. It is superfluous to point out the assistance the library gives in the choice of books, not only to the reader who relies on it for his whole supply, but on the book-lover and the purchaser of books. Of the aid offered to the student and the potential student, over and above the library organism itself as an efficient reading machine, more will be said under the heading of library extension. In American libraries certain members of the staff are told off for “floor duty,” that is, to keep a sympathetic eye on persons looking out books and to offer guidance. It is a duty calling for high attainments and insight into the particular requirements and idiosyncrasies of readers. It would be unfair to say it is a duty unfulfilled in libraries over here, since the more active public libraries are beginning to organize themselves as real bureaux of information; but in the precise form just described it is practically unknown. Our method is to be ready with advice when it is asked for; and in big libraries, such as the British Museum, it is the most useful kind of advice, that of the specialist, which is our particular forte. Yet we still repeat, “The librarian who reads is lost!” More specialism, not less, is what we want. NEWSROOMS AND MAGAZINE ROOMS.
