PREFATORY NOTE.

ere are plenty of treatises on classification, of which accounts may and in Edwards's Memoirs of Libraries and Petzholdt's Bibliotheca ographica. The classification of the St. Louis Public School Library ogue is briefly defended by W. T. Harris in the preface (which is ted, with some additions, from the Journal of Speculative Phihy for 1870). Professor Abbot's plan is explained in a pamphlet ed and in use at Harvard College Library, also in his "Statement ecting the New Catalogue" (part of the report of the examining aittee of the library for 1863), and in the North American Review anuary, 1869. The plan of Mr. Schwartz, librarian of the Appren'Library, New York, is partially set forth in the preface to his catae; and a fuller explanation is preparing for publication. For an or-catalogue there are the famous 91 rules of the British Museum* fixed to the Catalogue of Printed Books, Vol. 1, 1841, or conveniently nged in alphabetical order by Th. Nichols in his Handbook for ders at the British Museum, 1866); Professor Jewett's modification hem (Smithsonian Report on the Construction of Catalogues, 1852); F. B. Perkins's further modification (in the American Publisher for 9), and a chapter in the second volume of Edwards. But for a dicary-catalogue as a whole, and for most of its parts, there is no manwhatever. Nor have any of the above-mentioned works attempted set forth the rules in a systematic way or to investigate what might called the first principles of cataloguing. It is to be expected that rst attempt will be incomplete, and I shall be obliged to librarians criticisms, objections, or new problems, with or without solutions.

Compiled by a committee of five, Panizzi, Th. Watts, J. Winter Jones, J. H. Parry, E. Edwards, in several months of hard labor.

To these may now be added: Condensed rules for an author and title catalogue, pared by the co-operation committee, A. L. A. (printed in the Appendix of the sent Rules); F: B. Perkins's San Francisco cataloguing (1884); C: Dziatzko's Iniction für die Ordnung der Titel im alphabetischen Zettelkatalog der Univ. Bibliek zu Breslau (1886), of which an adaptation by Mr. K. A: Linderfelt will shortly published; Melvil Dewey's Condensed rules for a card catalogue, with 36 sample ds (published in the Library notes, v. 1, no. 2, 1886, and reprinted as "Rules for hor and classed catalogs;" with changes, additions, and a Bibliography of alog rules by Mary Salome Cutler, Boston, 1888, and again as "Library School es," Boston, 1889); G. Fumagalli's Cataloghi di biblioteche (1887); H: B. Wheat's How to catalogue a library (1889); and various discussions in the Library jour, the Neuer Anzeiger, and the Centralblatt für Bibliothekswesen.
