of perusing periodical works may be properly added to the catalogue of anti-mnemonics, or weakeners of the memory." If read sparingly, and for actual events, newspapers have a value which is all their own; but to spend hours upon them, as many do, is mere mental dissipation. CHAPTER 13. QUALIFICATIONS OF A LIBRARIAN. In directing attention to some of the more important elements which should enter into the character and acquirements of a librarian, I shall perhaps not treat them in the order of their relative importance. Thus, some persons might consider the foremost qualification for one aspiring to the position of a librarian to be wide knowledge in literature and science: others would say that the possession of sound common sense is above all things essential; others an excellent and retentive memory; still others might insist that business habits and administrative faculty are all-important; and others again, a zeal for learning and for communicating it to others. I shall not venture to pronounce what, among the multitude of talents that are requisite to constitute a good librarian is the most requisite. Suffice it to say, that all of them which I shall notice are important, and that the order of their treatment determines nothing as to which are more and which are less important. So much is expected of librarians that it actually appears as if a large portion of the public were of the opinion that it is the duty of him who has a library in charge to possess himself, in some occult or mysterious way, unknown to the common mind, of all the knowledge which all the books combine. The Librarian of the British Museum, speaking to a conference of librarians in London, quoted a remark of Pattison, in his "Life of Casaubon," that "the librarian who reads is lost." This was certainly true of that great scholar Casaubon, who in his love for the contents of the books under his charge, forgot his duties as a librarian. And it is to a large degree true of librarians in general, that those who pursue their own personal reading or study during library hours do it at the expense of their usefulness as librarians. They must be content with such snatches of reading as come in the definite pursuit of some object of research incident to their library work, supplemented by such reading time as unoccupied evenings, Sundays, and annual vacations may give them.
