REPORT OF NATIONAL MUSEUM, 1910. 67 
Besides the regular editorial work, there is a large amount of mis- 
cellaneous printing and _ binding, with all of which the editor’s office is 
also charged. The principal item is probably the furnishing of labels 
for both the exhibition and reserve collections. 
LIBRARY. 
The library of the Museum contains 38,300 volumes and 61,858 
unbound papers, the additions during the year having consisted of 
2,056 books, 5,541 pamphlets, and 307 parts of volumes. With 
an annual appropriation of but $2,000, which constitutes the only 
fund for purchasing, it is wholly impossible to maintain the library 
on the basis required for the study and classification of the collec- 
tions. In fact, except for the increment through exchanges and 
donations, the working benefits of the library would be very inad- 
equate, and this in spite of the fact that the Library of Congress 
and several Department libraries are freely placed at the service 
of the Museum. Among Museum officers and associates who made 
important gifts to the library durmg the year were Dr. Theodore N. 
Gill, Dr. Charles A. White, Dr. Charles W. Richmond, Mr. E. A. 
Schwarz, Dr. O. P. Hay, and Dr. Marcus Benjamin. 
In common with all other branches of the Museum, the limited 
quarters assigned to the library have become more and more con- 
gested each year, interfering with the continued systematic arrange- 
ment of the publications, and causing inconvenience in cataloguing 
and other parts of the work. For this condition a remedy will be 
found during the coming year, in the more ample space which it 
will be possible to allot to this subject. Good progress was made 
in the cataloguing of publications, and volumes to the number of 
435 were prepared and sent to the Government Printing Office for 
binding. Each of the divisions and principal offices of the Museum 
has a sectional library, consisting of the works pertaining specially 
to its province, and these are supervised by the central library, in 
which they are recorded the same as is the main body of publications. 
There are 29 of these sectional libraries. 
PHOTOGRAPHY. 
The alterations mentioned in the last report as necessary to place 
the photographic laboratory in a condition to meet the increased 
work and to generally improve its facilities were commenced at the 
beginning of the year and completed during the summer. They 
included a new skylight, new side lights for use with the photo- 
microscope, and an extension over the adjoining lower roof for 
blue printing. For the purposes of a museum this laboratory is 
probably not surpassed in the country as regards both its general 
arrangements and its equipment.
