STUDIES ON MUSEUMS AND KINDRED INSTITUTIONS. 467 



rare collection of American and English hynni books. Finall}^ art 

 and humanistic sciences (50, 51), with subsections of art, literature, 

 and languao-es." I will mention 324 lexicons in " almost all languages." 



In the third story is the department of science (71), with subsections 

 of natural science, Congressional documents, bound newspaper files, 

 and special collections. The union of such a mixture under a depart- 

 ment of science is not exactly happy. I will mention as specialties 

 1,200 volumes on China, 1,882 numbers on fishes, fish culture and 

 angling, Egyptian and sporting collections. There is also found in 

 the third story genealogy, and the musical library (57), with scores of 

 the great composers, works on the history and theorj' of music, as 

 well as on instruments, together with critical papers, journals, biog- 

 raphies; also lexicons and cyclopedias in "alP' languages, and finally, 

 works on the early Greek music and the early Italian writers. The 

 principal item of interest is the musical collection of Count Pio Resse 

 in Florence, which was bought in 1888. Recently the well-known 

 American musician, Theodore Thomas, gave to this institution his 

 great musical library. Finally, there are in the third story three lec- 

 ture rooms (63-65) that hold 100 persons each, and a hall (56) which is 

 temporarily assigned to the Friday Club, the most exclusive literary 

 and social woman's club in Chicago. 



In the fourth story is the well-appointed bookbinderv (78) — ever}^- 

 thing is bound in the building. The rest of the rooms, except one for 

 duplicates (73), are vacant. 



On either side of the principal stairway there is a passenger eleva- 

 tor from the basement to the fourth story, besides a book elevator at 

 another place, as shown in the plans, figs. 48-52. 



The installation and marking of the books is done according to Cut- 

 ter's seventh system '^ with some modifications. Ever}- section has the 

 Cutter letters and numbers and to this is added an author's number 

 according to a special list of the Newberry LibraiT. The books stand 

 in the order of their numbers, as in the Dewey decimal system. 



The method of cataloguing of this librar}^ is quite peculiar and 

 extremely ingenious, and is according to the system invented by the 

 assistant librarian, A. J. Rudolph, a Hungarian, who from 1879 to 

 1894 was assistant librarian in the San Francisco Free Public Librar^^

« In June, 1901, the Newberry Library purchased the well-known Lil)rary of Prince 

 Louis Lucien Bonaparte, who died in 1891. It contsiined 15,000 vohinies on 

 European languages. Negotiations for this lasted two years. It is a most important 

 acquisition.

 Classification. Transactions and Proceedings of the Second International Library 

 Conference, London, 1897 (1898), pp. 84-88. "Expansive Classification" signifies a 

 scheme of seven tables of classification of progressive fullness, designed to meet the 

 needs of a library at its successive stages of growth, therefore "expansive."
