152 REPORT OF NATIONAL MUSEUM, 1914. 
of Montana, with note on Hypacrosaurus,” by Charles W. Gilmore; 
and “ Explorations and field-work of the Smithsonian Institution in 
1912,” being a summary of expeditions participated in during the 
year by the Smithsonian Institution and its bureaus and resulting, 
for the most part, in the acquisition of material for the Museum. 
In addition to the publications, the editorial office has charge of all 
miscellaneous printing and binding, which includes a large variety of 
work. 
LIBRARY. 
The Museum library received 1,917 volumes, 1,723 pamphlets, and 
132 parts of volumes during last year, and now contains 43,609 vol- 
umes and 73,765 pamphlets and other unbound papers. The central 
library is in the new building, where are kept the general works of 
reference and the publications relating to anthropology, zoology, and 
geology. The former library quarters in the older building are 
utilized for the works relating to the arts and industries, history, and 
botany, besides which each Museum division and each principal ad- 
ministrative office is allowed to retain in its immediate possession the 
books especially and solely pertaining to the subject of its affairs. 
The last mentioned, which at present number 30, are called sectional 
libraries. The central library was quite thoroughly organized and 
arranged before the close of the previous year, and during last year 
good progress in the same direction was made with the collection in 
the older building. The card cataloguing has been kept well up to 
date and of the scientific depository set of cards received from the 
Library of Congress about one-half, or approximately 28,000, were 
alphabetically filed. 
For the use of the staff in the study of collections over 5,000 books 
were borrowed during the year from other Government libraries, 
mainly the Library of Congress. 
A very large number of publications, the accumulation of many 
years, the most of which had never been actually united with the 
library, were critically examined and the greater proportion, consist- 
ing of duplicates or of works not necessary to the Museum, were 
rejected and disposed of. 
New avenues of exchange insuring the acquisition of important 
publications not otherwise obtainable by the Museum were estab- 
lished. By bequest of Miss Lucy H. Baird, the library received 
about 750 volumes, many of them rare and costly, which had be- 
longed to Prof. Spencer F. Baird, with others more recently added 
to the collection by the testator. Among other contributors were 
Dr. William H. Dall, Dr. O. P. Hay, Dr. C. W. Richmond, Dr. Edgar 
A. Mearns, Mr. Alfred Klakring, and Dr. Harriet Richardson Searle.
