scope of the new undertaking. It is expected to contain about two 
million entries, including, however, a number of cross-references from 
editors, translators, etc. 
One of the most notable of European library catalogues is that in 
use at the Royal Library at Breslau. Dr. Dziatzko, formerly librarian 
at Breslau, and now of the University of Gottingen, originated this cata- 
logue. Dr. Dziatzko’s system, which has already been mentioned as the 
main source of Linderfelt’s Code, was itself founded upon the British 
Museum rules, with certain important modifications. The Breslau 
catalogue is not a book catalogue, like that of the British Museum, 
but a card catalogue. 
The dictionary catalogue is peculiarly an American invention, and 
very few specimens are to be found outside of the United States. One 
may be mentioned, however, the “Analytical and Classified Catalogue 
of the Library of Parliament of Queensland,” 1883, prepared by Mr. 
D. O'Donovan, Parliamentary Librarian. The books are entered under 
author and subject with full cross-references, and all the entries are 
arranged in one alphabet. There are abstracts of the contents of some 
of the books, and references to articles in reviews. The finest example 
of this type of catalogue is, of course, that of the Surgeon-General’s 
Office, Washington, but the tremendous amount of money and labour 
expended upon this catalogue makes it improbable that any other library 
will attempt to carry out the dictionary principle so exhaustively. 
Mr. Cutter, in the introduction to his “ Rules for a Dictionary 
Catalogue,” gives the following analysis of this form of catalogue :—It 
must embody: Author-entry, title-entry or title-reference, subject-entry, 
cross-references and classed subject table, form-entry, the edition and 
imprint, with notes bibliographical and literary where necessary. It is 
designed to serve the following purposes: To enable a person to find a 
book of which either the author, the title, or the subject is known. To 
show what a library has, by a given author, on a given subject, or in a 
given kind of literature. To assist in the choice of a book, as to its 
edition (bibliographically), or, as to its character (literary or topical). 
The dictionary catalogue includes practically the advantages of 
every other kind of catalogue. It answers every legitimate question that 
the reader or student may ask as to the books of which it is the record. 
It is, therefore, if properly constructed, of inestimable benefit to the 
constituents of any library, large or small. 
The arrangement of books upon the shelves may be roughly divided 
into two classes : the fixed location system ; and the relative location. 
The former has been adopted at the British Museum, the Bodleian, and 
most of the larger libraries of England and the Continent. About the 
only American library which uses it is that of Cornell University. The
