also 29 electrically regulated clocks distributed throughout the library.

In the year 11)0(1-1901 (the tiscal year extends from June 1 to May 

 31) there were on hand 272,276 ])ound volumes and 49,805 unbound 

 pamphlets, as well as over 6,000 duplicates. The following catalogues 

 were kept up with the greatest care: (1) An accession catalogue with 

 running numbers; (2) a shelf catalogue according to a special system 

 founded on Cutter's classification, with letters indicating subjects and 

 with running numbers according to which the books are arranged 

 (the tags are pasted upon the backs); (8) an alphabeticjil card cata- 

 logue of authors, titles, and subjects combined (dictionary catalogue), 

 there being two copies of this, one for the use of the employees

and one for the })ublic, in the room adjoining the book room of the 

 third story. Each catalogue is kept in a wooden case with 500 draw- 

 ers" that hold nearl}^ 500,000 cards; 200,000 in each are alread}^ in use. 

 The cards for use by the public are perforated and strung on a metal 

 rod so secured (in the well-known manner) that the user can not remove 

 them. The catalogue for use by employees is not so confined. All 

 the cards in use in American libraries are of a uniform size of 3 by 5 

 inches. In the Chicago Pul)lic Library some of the cards are written 

 with the pen, some with the typewriter, but many are bought ready 

 printed. Printed catalogues, which for the small sum of 3 to 15 cents, 

 can be bought in the library itself, and in all branch stations, are pre- 

 pared for the use of the public* 



"Such card catalogue cases are also made in America, out of iron, especially by 

 the Art Metal Construction Company, of Jamestown, from which the Dresden Zoo- 

 logical Museum obtained a small one.
