Vr (5 ' 4- American Library Institute 1921 Preprint. SHORT CATALOGUING AND BIBLIOGRAPHICAL CATALOGUING. By Henry Bartlett Van Hoesen. While the factors entering into a library catalogue are common the world over, the degree in which they enter in is by no meanuniform. Even in a single library there is admittedly plenty of lack of uniformity between theory and practice. The dictionary definition of catalogue, taken in connection with this dis- cussion and the present methods of cataloguing, is interesting, if not even amusing: "(1) A list, register, or complete enumeration; in this simple sense now obsolete or archaic". "(2) Now usually distinguished from a mere list or enumeration by systematic or methodical arrangement . . . and often by the addition of brief particulars, descriptive or aiding identifica- tion." The second definition is probably as old as the first, since the earliest catalogue I have any intimate acquaintance with. Homer's "Catalogue of Ships," verges on literary description and Kallimachus is said to have done some of his cataloguing of the Alexandrian Library in poetry. So true, however, is the remark in the first definition about the obsoleteness of cata- loguing in its simple meaning that one recent library manual defines cata- loguing as book description. This definition is, I submit, a rather dangerous one. Book description is rather a definition of bibliography, the interest of which is the book itself rather than any library or the actual finding of the book. The object of this paper is, however, not a comprehensive definition of catalogue but a rough definition or distinction of two kinds of library cata- logue; the one "a list, register or complete enumeration in systematic ar- rangement, with addition of brief particulars aiding identification and loca- tion"; the other, descriptive. That is, the minimum library catalogue must suffice for inventory and location. This is, theoretically, the catalogue proper or short catalogue ; the rest of the information on the cards may be called bibliographical (in a general sense, since literary, scientific, and criti- cal material are sometimes included in the "annotations"). 1 477^94 2
