Johnson's notion as to the collection of editions which are alike except in the point of paper is scarcely sound, but it has been held by a librarian of the present day, as I know to my cost. On one occasion I was anxious to see several copies of the first folio of Shakespeare (1623), and I visited a certain library which possessed more than one. The librarian expressed the opinion that one was quite sufficient for me to see, as "they were all alike."

The possessor of a Private Library can act as a censor morum and keep out of his collection any books which offend against good morals, but this role is one which is unfit for the librarian of a Public Library. He may put difficulties in the way of the ordinary reader seeing such books, but nevertheless they should be in his library for the use of the student. A most amusing instance of misapplied zeal occurred at the Advocates' Library on the 27th June, 1754. The Minutes tell the tale in a way that speaks for itself and requires no comment. "Mr. James Burnet [afterwards Lord Monboddo], and Sir David Dalrymple [afterwards Lord Hailes], Curators of the Library, having gone through some accounts of books lately bought, and finding therein the three following French books: Les Contes de La Fontaine, L'Histoire Amoureuse des Gaules and L'Ecumoire, they ordain that the said books be struck out of the Catalogue of the Library, and removed from the shelves, as indecent books, unworthy of a place in a learned Library."

At a Conference of Representatives of Institutions in Union with the Society of Arts held in July, 1855, the question of the compilation of a Catalogue of Books fitted for the Libraries of Institutions was raised, and shortly afterwards was published, under the sanction of the Council, "A Handbook of Mechanics' Institutions, with Priced Catalogue of Books suitable for Libraries, and Periodicals for Reading Rooms, by W.H.J. Traice." A second edition of this book was published in 1863. The list, however, is not now of much use, as many of the books have been superseded. Theology and Politics are not included in the classification.

In 1868 Mr. Mullins read a paper before a Meeting of the Social Science Association at Birmingham, on the management of Free Libraries, and, in its reprinted form, this has become a Handbook on the subject: "Free Libraries and News-rooms, their Formation and Management. By J.D. Mullins, Chief Librarian, Birmingham Free Libraries. Third edition. London, Sotheran and Co., 1879." An appendix contains copies of the Free Libraries Acts and Amendments, and a "Short List of Books for a Free Lending Library, ranging in price from 1s. to 7s. 6d. per volume."

Mr. Axon read a paper on the Formation of Small Libraries intended for the Co-Operative Congress in 1869, which was reprinted as a pamphlet of eight pages: "Hints on the Formation of Small Libraries intended for Public Use. By Wm. E.A. Axon. London, N. Trübner and Co."

Mr. A.R. Spofford has given a valuable list of books and articles in periodicals, on the subject of Libraries in chapter 36 (Library Bibliography), of the Report on Public Libraries in the U.S. (1876).

The volume of Transactions and Proceedings of the Conference of Librarians, London, 1877, contains two papers on the Selection of Books, one by Mr. Robert Harrison, Librarian of the London Library, and the other by the late Mr. James M. Anderson, Assistant Librarian of the University of St. Andrews. Mr. Harrison gives the following as the three guiding principles of selection in forming a library: 1. Policy; 2. Utility; 3. Special or Local Appropriateness; and he deals with each successively. Mr. Anderson writes that "the selection of books should invariably be made (1) in relation to the library itself, and (2) in relation to those using it."

We have chiefly to do with the formation of libraries, and therefore the use made of them when they are formed cannot well be enlarged upon here, but a passing note may be made on the proposal which has been much discussed of late years, viz. that for Professorships of Books and Reading. The United States Report on Public Libraries contains a chapter on this subject by F.B. Perkins and William Matthews (pp. 230-251), and Mr. Axon also contributed a paper at the First Annual Meeting of the Library Association. The value of such chairs, if well filled, is self-evident, for it takes a man a long time (without teaching) to learn how best to use books, but very special men would be required as Professors. America has done much to show what the duties of such a Professor should be, and Harvard College is specially fortunate in possessing an officer in Mr. Justin Winsor who is both a model librarian and a practical teacher of the art of how best to use the books under his charge.

CHAPTER I.

How Men have Formed Libraries.

As long as books have existed there have been book collectors. It is easy now to collect, for books of interest are to be found on all sides; but in old times this was not so, and we must therefore admire the more those men who formed their libraries under the greatest difficulties. In a book devoted to the formation of libraries it seems but fair to devote some space to doing honour to those who have formed libraries, and perhaps some practical lessons may be learned from a few historical facts.

Englishmen may well be proud of Richard Aungerville de Bury, a
