REPORT OF THH SECRETARY 125 
MUSEUM LIBRARY 
During the year the library of the National Museum was increased 
by 1,660 volumes and 1,466 pamphlets, making a total of 66,808 vol- 
umes and 104,417 pamphlets. Most of the accessions were, of course, 
obtained by exchange, but some were obtained by purchase and an 
unusually large number by gift. The largest gift was from the 
Library of Congress. This comprised 606 volumes and 808 parts 
of volumes from its collection of duplicates—some stamped Smith- 
sonian Deposit, others Library of Congress—and was sent to the 
Museum library to help complete its sets of society publications per- 
taining mainly to natural history. Generous gifts were also received 
from Secretary Walcott, who, as usual, contributed hundreds of items 
to the library, particularly to the section of geology and paleontol- 
oxy; Dr. W. H. Holmes, who gave 83 volumes and 363 pamphlets to 
the general collection; Dr. W. H. Dall, who added 178 titles to the 
section of mollusks; Dr. C. W. Richmond and Mr. J. H. Riley, who 
gave many books and pamphlets, some of them very rare, to the main 
collection, as well as to the section of birds and other sections; and 
Mr. N. M. Judd, who contributed 18 volumes to the section of Amer- 
ican archeology. Among other donors were Assistant Secretary 
Wetmore, Mr. A. N. Caudell, Mr. John Gallagher, Dr. O. P. Hay, 
Dr. A. Hrdlicka, Dr. W. R. Maxon, Dr. G. S. Miller, Mr. S. A. 
Rohwer, and Dr. W. Schaus. 
The number of sectional libraries in the Museum is now 87. These, 
while in a measure independent working units, are in a real sense 
very important parts of the general library. During the year the 
study of their resources and problems that was begun the year before 
was continued, with a view to strengthening their collections and 
making them more available. The sectional libraries are as follows:
